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:$C014 for axis 1-4
(1
st
PMAC2 Gate), and X:$C024 for axis 5-8 (2
nd
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.
