Configuration of motor control-related functions. For motors above 200 Hz, a carrier frequency of 8 kHz or higher is recommended. Consider drive derate and motor

lead distance restrictions.

Bit 0 “Zero TrqStop” – Configures stopped condition when in torque mode. 0 = wait for zero speed before shutting off drive output, 1 = wait for zero torque before

shutting off drive output.

Bit 1 “Trq ModeStop” – Configures stopping behavior when in torque mode. 0 = remain in torque mode, 1 = switch to speed mode

Bit 2 “Trq ModeJog” – Configures jogging behavior when in torque mode. 0 = remain in torque mode, 1 = switch to speed mode

Bit 3 “EnclsTrqProv” – Enables encoderless mode when using the torque prove function. 0 = Disabled, 1 = Enabled. Bits 0 and 1 of P1100 [Trq Prove Cfg] must also

be set to use this mode.

Bit 4 “Mtr Lead Rev” – Reverses the phase rotation of the applied voltage, effectively reversing the motor leads. 0 = Not Reversed, 1 = Reversed

Bit 5 “Reflect Wave” – Enables reflected wave voltage protection for long motor cables. 0 = Disabled, 1 = Enabled

Bit 6 “RS Adaption” – Adapts for changes in motor stator resistance due to motor temperature. Active only in FV motor control mode with feedback. 0 = Disabled, 1

= Enabled

Bit 7 “PWM Type Sel” – Configures 3 Phase / 2 Phase switching of the power devices. 0 = 3 Phase modulation with auto switchover to 2 phase modulation. 1 = Full

time 3 phase modulation (no switchover)

Bit 8 “AsyncPWMLock” – Configures Synchronous / Asynchronous switching of the power devices. 0 = Automatically changes between synchronous and

asynchronous. 1 = Asynchronous switching only.

Bit 9 “PWM FreqLock” – Configures switching frequency of the power devices while in FV motor control mode without feedback. 0 = switching frequency

automatically reduces to 2 kHz at low speeds (best performance), 1 = switching frequency does not reduce (setting used when switching frequency reduction is

undesirable)

Bit 10 “DB WhileStop” – Enables operation of the dynamic brake transistor while the drive is stopped. 0 = Disabled, 1 = Enabled

Bit 11 “Elect Stab” – Enables stability control for Sensorless Vector and V/Hz motor control modes. 0 = Disabled, 1 = Enabled

Bit 12 “Xsistor Diag” – Enables power transistor diagnostic test at each start command. Recommended to set to Disabled if an output filter is installed with the

drive. Refer to publication PFLEX-AT002

for additional information. 0 = Disabled, 1 = Enabled

Bit 13 “Common Mode” – Enables the common mode reduction modulator to reduce the common mode voltage generated by the pulse width modulated inverter.

Bit 15 “Jerk Select” – Limits the rate of change to the velocity reference for improved current limiting. This setting applies only to Sensorless Vector and V/Hz motor

control modes. 0 = Disabled (0.0 second ramp time achievable), 1 = Enabled (0.0 second ramp time prevented)
