O
PERATIONAL MODES
The motor servo has a number of operational modes controlled by the motor mode register MOTOR4.
P
OWER LIMIT
To start and stop the spindle motor, a fixed positive or negative voltage is applied to the motor. This voltage can be
programmed as a percentage of the maximum possible voltage via the motor output configuration register (MOTOR4) to
limit current drain during start and stop. The following power limits are possible:
100% of maximum (no power limit)
75% of maximum
50% of maximum
37% of maximum.
L
OOP CHARACTERISTICS
The gain and crossover frequencies of the motor control loop can be programmed via the motor gain and bandwidth
register MOTOR2.
