Any wire chosen must have a minimum insulation thickness of 15 mils and should not have large variations in insulation concentricity.
Page 20 If it is necessary to disconnect power to the motor with the drive outputting power, an auxiliary contact should be used to simultaneously disable drive control run commands. Page 21 Drive will not power up without a jumper or inductor connected. Page 22 When the AC line is removed, there will be a loss of any inherent regenerative braking effect that might be present - the motor will coast to a stop. An auxiliary braking method may be required. Page 26 Each digital input draws 6 mA.
Page 27 Direction Mode]. Each digital input draws 6 mA. All drives must be powered up for the analog signal to be read correctly. Run as specified by P [Speed Reference]. Start and Direction commands come from P [Start Source]. Page 30 Preset Frequency.
Page 32 Keep wire length as short as possible between the enclosure entry point and the EMI filter. Page 33 Installations on a public low voltage power network may require additional external harmonic mitigation. To simplify drive setup, the most commonly programmed parameters are organized in a single Basic Program Group. Important: Read the General Precautions section before proceeding. Page Integral Keypad Scroll through groups and parameters.
Down Arrow Enter Advance one step in programming menu. Save a change to a parameter value. Press the Up Arrow or Down Arrow to scroll through the parameters in the group. Page 39 [Output Frequency] is displayed. Press Enter or Sel to enter the group menu again.
The Basic Program Group page contains the most commonly changed parameters. Parameters marked 32 bit will have two parameter numbers when using RS communications and programming software.

Page 51 Values Default A valid start will override this command. Values Default 0. Page 55 Enables the output to be controlled by bit 6 of the logic command word. Page 56 [Relay Out Sel] is 6, 7, 8, 10 or Page Communications Group Stops drive via coast to stop.
Page 58 Do not create a program that frequently uses configurable outputs to write parameter data to NVS unless C [Comm Write Mode] is set to option 1. Values Default Page 61 Sets the frequency at which the drive will not operate. A setting of 0 disables this parameter. Values Default P [Maximum Freq] De n ratio. When Enabled, the value held in the motor overload counter is saved at power-down and restored at power-up. A change to this parameter setting resets the counter.
P [Reset To Defalts] Stop drive before changing this parameter. Resets all parameter values to factory defaults.
Important: Digital Inputs have priority for frequency control when programmed as a Preset Speed and are active. Refer to the flowchart on for more information on speed reference control priority. A valid start will override this command. Start Cont. This indicates Default that the drive is ready for operation. Relay returns drive to shelf state when power is removed or a fault occurs. Important: Value for t [Relay Out Level] must be entered in percent of drive rated output current.
Sets the trip point for the digital output relay if the value of t [Relay Out Sel] is 6, 7, 8, 10 or Communications Group C [Language] Selects the language displayed by the remote communications option. Important: Power to drive must be cycled before any changes will affect drive operation.
Values Default 5. Refer to Appendix C for details on using the drive communication features. If they are stored in RAM, the values will be lost at power-down. Do not create a program that frequently uses configurable outputs to write parameter data to NVS unless C [Comm Write Mode] is set to option 1. Refer to the flowchart on page for details. A [Decel Time 2] Related Parameter s : P When active, sets the rate of deceleration for all speed decreases except jog.

See the diagram below. A setting of 0. Values Default: 0. Drive Output Frequency. Motors may be demagnetized during braking. This parameter applies only to Frame C drives.
The drive is able to provide full braking indefinitely. Braking power is limited by the external DB resistor. C , the drive provides calculated resistor overload protection. However, the drive cannot protect against a brake IGBT failure.
The external resistor package must be self-protected from over temperature or the protective! Selects the duty cycle allowed for an external dynamic braking resistor when A [DB Resistor Sel] is set to 3. Requires a digital input configured for Run or Start and a valid start contact. Do not use this function without considering! The reverse command may come from a digital command, the keypad or a serial command. All reverse inputs including two-wire Run Reverse will be ignored with reverse disabled.
This setting attempts to correct this condition. This setting slows down the current regulator response and attempts to correct this condition. This frequency is added to the commanded output frequency based on motor current. Values Default 2. When set to a value other than zero, d [Process Display] indicates the duration of the process. A [Bus Reg Mode] Controls the operation of the drive voltage regulation, which is normally operational at deceleration or when the bus voltage rises.
Refer to the Attention statement on page P-3 for important information on bus regulation. A [Current Limit] Maximum output current allowed before current limiting occurs. Settings select the derating factor for the I2t overload function. The chart below provides derating guidelines based on the PWM frequency setting. Important: Ignoring derating guidelines can cause reduced drive performance.
Values Default 4. Resets a fault and clears the fault queue. Used primarily to clear a fault over network communications. A [Auto Rstrt Tries] Sets the maximum number of times the drive attempts to reset a fault and restart.
Clear a Type 1 fault and restart the drive. Values Default 1. A [Program Lock] Protects parameters against change by unauthorized personnel. Troubleshooting Chapter 4 provides information to guide you in troubleshooting the PowerFlex 4M drive. Included is a listing and description of drive faults with possible solutions, when applicable. Drive Status The condition or state of your drive is constantly monitored. Any changes will be indicated through the integral keypad. When the timer reaches zero, the drive attempts to automatically reset the fault.
If the condition that caused the fault is no longer present, the fault will be reset and the drive will be restarted. The cause of the fault must be corrected before the fault can be cleared. Fault Indication Condition Display Drive is indicating a fault. The integral keypad provides visual notification of a fault condition by displaying the following. Manually Clearing Faults Step Key s 1. Press Esc to acknowledge the fault. The fault information will be removed so that you can use the integral keypad.
Access d Fault 1 Code to view the most recent fault information. Address the condition that caused the fault. The cause must be corrected before the fault can be cleared. See Table 4. After corrective action has been taken, clear the fault by one of these methods. Only certain faults are allowed to be reset.
Certain faults Type 2 that indicate possible drive component malfunction are not resettable. Caution should be used when enabling this feature, since the drive will attempt to issue its own start command based on user selected programming. Fault Descriptions Table 4.
