Installation manual

Geo Direct PWM Amplifier
Drive Command Structure 47
Enhanced Mode
Enhanced mode enables access to and control of additional functions:
 Bus voltage reading
 IGBT temperature(s) reading
 Set PWM control for brush motor
 Turn Line Monitor off
Caution
The drive must be put in enhanced mode before accessing the
additional functions.
Caution
Once the drive is set up for enhanced mode, do not set it back to
default mode until the next logic power cycle.

With Power PMAC3, setting the drive to enhanced mode requires the following motor setting changes:
 Motor[x].PhaseCtrl = 4
 Gate3[i].Chan[j].PackInData = 0
 Gate3[i].Chan[j].PackOutData = 0
Note
Once in enhanced mode, the drive’s communication will remain in
enhanced mode until the next logic power cycle.
