Using the /CLT Signal
The following section describes the use of the contact output signal /CLT as a torque
limit output signal.
Photocoupler output
Maximum operating voltage
per output: 30VDC
Maximum operating current
per output: 50mADC
Output ð /CLT CN1-*1
This signal indicates whether servomotor output torque (current) is being limited.
Status
The circuit between CN1–*1 and *2
is closed.
ON
CN1–*1 is at low level.
The circuit between CN1–*1 and *2
is open.
OFF
CN1–*1 is at high level.
Settings:
When the /CLT signal is used, the following parameter must be used to select the
output signal.
Parameter
Pn50F
Output Signal Selections 2
Torque limit
Too small a torque limit will result in a
insufficient torque during acceleration and
deceleration.
