Geo Direct PWM Amplifier

Power PMAC2 Drive Setup 40

POWER PMAC2 DRIVE SETUP

Caution

The ADC Strobe Word, Gate1[i].AdcStrobe, must be set to $3FFFFF

for proper operation in default mode. Failure to do so 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:

Structure Element

Description

Typical/Default

Notes

Gate1[i].PwmPeriod

PWM Frequency

6527

4.50 KHz PWM

Gate1[i].PhaseClockDiv

Phase clock divider

9.00 KHz Phase

Gate1[i].ServoClockDiv

Servo clock divider

2.25 KHz Servo

Gate1[i].HardwareClockCtrl

Hardware Clocks

2258

2.50 MHz ADC Clock

Sys.ServoPeriod

= 1000 * (Gate1[4].ServoClockDiv + 1) / 18000

Sys.PhaseOverServoPeriod

= 1 / (Gate1[4].ServoClockDiv + 1)

Gate1[i].AdcStrobe

ADC Strobe Word

$3FFFFF

Default Mode

Gate1[i].Chan[j].OutputMode

Output mode

PWM output

Note

Sys.ServoPeriod and Sys.PhaseOverServoPeriod 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.
