During this tuning process, P2Setup also determines the commutation parameters and commands the
PMAC appropriately.

applicable.
F.A.Q
1. PWM Frequency – The default value suggested by P2Setup (4.5 kHz) works well for most
applications. If more heat is generated in the motor than the amplifier, using a higher PWM frequency
may assuage this problem.
a. Set up a Lower Voltage Motor with the Quad Amplifier. The following steps should be
followed in P2Setup to ensure that the appropriate voltage is used for the motor while using the
Quad Amplifier:
After PWM frequency and Phase and Servo frequencies have been set up successfully, click the
Terminal Window tab.
Modify Ix66 using the following formula:
Voltage_Bus_Amp_Quad
voltage_peak_Motor*900I
