Geo Direct PWM Amplifier

Turbo PMAC2 Drive Setup 43

TURBO PMAC2 DRIVE SETUP

Caution

The ADC Strobe Word, I7m06 ($C014 in Non-Turbo PMAC), must

be set to $3FFFFF for proper operation in default mode. Failure to set

I7m06 equal to $3FFFFF could result in damage to the amplifier.

Key Gate Parameters

The following Gate-specific parameters are essential for the proper software setup of the Geo Direct

PWM Drive:

Turbo

Non-Turbo

Note

Non-Turbo ADC Strobe words are at addresses X:$C014 for axis 1-4

PMAC2 Gate), and X:$C024 for axis 5-8 (2

PMAC2 Gate).

Note

The servo interrupt time I10 must be re-computed if the main clocks

(Phase, PWM, and Servo) are changed.

Note

The above settings require a Save and a Reset ($$$) on the PMAC

side in order to take effect.
