Torque

Factory

Setting:

Maximum

Torque

Valid when Cn-01 bit 8

= 1

Specifies the stop torque to be applied at overtra-
vel when the input signal for prohibiting forward or
reverse rotation is to be used.

Specifies a torque value in terms of a percentage
of the rated torque.

Cn-01 Bit 6

How to Stop Motor at Servo

OFF

Factory

Setting: 0

Cn-01 Bit 7

Operation to Be Performed

when Motor Stops after Servo

OFF

Factory

Setting: 1

Invalid for 2.0 kW or more

The SERVOPACK enters servo OFF status when:

• Servo ON input signal (/S-ON, 1CN-40) is

turned OFF.

• Servo alarm arises.

• Power is turned OFF.

Specify how to stop the motor when one of the
above events occurs during operation.

Setting

Meaning

C 01

0

Stops the motor by dynamic brake.

Cn-01

bit 6

1

Causes the motor to coast to a stop.
The motor power is OFF and stops due to machine friction.

If dynamic brake stop mode is selected, specify the operation to be performed when the
motor stops.

Setting

Meaning

Cn-01

0

Releases dynamic brake after the motor stops.

Cn-01

bit 7

1

Does not release dynamic brake even after the motor stops.

Note

For SERVOPACKs of 2.0 kW or more, bit 7 of Cn-01 can be set to 0 only.

Dynamic brake is a function that

electrically applies brakes by using a

resistor to consume motor rotation

energy.
