S
Does the reference speed match the actual motor speed?
S
Does the motor stop when no reference is input?
Un-00 Actual motor speed
Un-01 Reference speed
3. If the motor rotates at an extremely slow speed when 0 V is specified as the reference
voltage, correct the reference offset value as described in Section 4.2.4 Reference
Offset Automatic Adjustment
4. To change motor speed or the direction of rotation, reset the parameters shown be
low.

SERVOPACK for Position Control
1. Set parameter Cn-02 so that the reference pulse form matches the host controller out-
put form. (See page 183 for details on how to set parameters.)
Selecting reference pulse form (See page 70)

2. Input slow speed pulses from the host con-
troller and execute low-speed operation.
3. Check the following items in monitor mode
(see page 191):
S
Has a reference pulse been input?
S
Is the motor speed as designed?
S
Does the reference speed match the actual motor speed?
S
Does the motor stop when no reference is input?
Un-00 Actual motor speed
Un-07 Reference pulse speed display
Un-08 Position error
4. To change motor speed or the direction of rotation, reset the parameters shown as
follows.
