Power On/Off Procedures 34

POWER ON/OFF PROCEDURES

Caution

Changing the ADC clock on the controller (PMAC) side requires

recycling power on the Geo Direct PWM Drive.

Caution

Main bus power should NEVER be applied if the 24V logic power is

NOT applied.

Caution

Make sure that no motor commands (e.g. phasing, jogging, or open

loop) are being executed by or sent by the controller (PMAC) at the

time of applying main bus power.

 Powering up the Geo Direct PWM Drive must obey the following procedure:

1. Make sure that PMAC is powered up, and that the PWM cable is connected

2. Apply 24V logic power to the Geo Direct PWM Drive

3. Wait a minimum of ~3 seconds

4. Apply main bus power

5. Wait ~ 3seconds before enabling the drive (motor)

 Powering down the Geo Direct PWM Drive must obey the following procedure:

1. Disconnect main bus power

2. Wait a minimum of ~5 seconds

3. Disconnect 24V logic power

Cycling Main Bus Power

Caution

Main bus power should NEVER be applied or cycled if the 24V logic

power is NOT applied.

Cycling main bus power must obey the following warning restrictions. A delay should be inserted in

either software, hardware or both to ensure that these restrictions are conformed.

Caution

Do NOT to cycle main bus power frequently and rapidly within a few

seconds.
