Geo Macro Drive –
Setting PWM Scale Factor (Ixx66)
Due to the specific nature of the Geo Macro
drive’s PWM generation, the Ixx66 parameter in Turbo PMAC must always
be set to 16384 for a motor xx
commanding a Geo Macro Drive. There is no need to modify this value for
any reason when using a Geo
Macro Drive.
If the Ixx66 parameter is left in
its default state of 6527 the motor may not be able to achieve
maximum speed and torque. Setting
Ixx66 to a value less than the recommended 16384 will act as a voltage
limit and can result in perceivable performance degradation.
