SEt-44(1) Dynamic Brake<br />

• Setting range: 0 x 0 to 0 x 1<br />

• <strong>User</strong> Default: 0 x 0<br />

• Changes while the servo is OFF<br />

The set values are as follows.<br />

0: Stop the motor with dynamic brake<br />

1: Stop the motor with free run<br />

If a motor shaft is revolved manually after short-circuiting all the motor<br />

cables (U, V, W) of the servo motor, the revolving load is higher than<br />

when the cables are not short-circuited. The drive uses this feature to<br />

stop the motor. When the servo drive uses this feature to stop the<br />

motor, it is called dynamic brake.<br />

<strong>CSDP</strong> <strong>Plus</strong> servo drive has internal dynamic brake circuit.<br />

If the motor cable is connected to the servo drive and the servo drive is<br />

not enabled, the switch in the diagram below is short-circuited. This<br />

means dynamic brake is working. And the servo drive can activate<br />

dynamic brake by controlling the switch of dynamic brake according to<br />

the parameter setting.<br />

ATTENTION<br />

Dynamic brake cannot be used with the motor stop method<br />

which uses normal torque control.<br />
