Microdrive Series Instruction Manual

4201-109 Rev I

MOTOR HEATER

Screen

28 DC HEAT =OFF

Description

DC HEATING VOLTAGE DURING STOP

Min/Max

OFF/0.1/10

Units

%V(MOTOR)

FUNCTION

To provide standby (anti-condensation) heating

of the motor by means of a small DC current.

When enabled, a DC heating current flows in

the motor whenever the Microdrive is stopped.

Any fault causing a trip disables DC heat.

SETTING UP

If not required, leave OFF.

If required, adjust the DC heat level while the

Microdrive is stopped, until approximately 10

25% of rated current flows in the motor.

WARNING:

High voltage will be present on the motor

terminals while DC heating is employed.
