5-5 Electromagnetic Brake Setting

- SV Series User’s Manual -

COMMON PARAMETER SETTING

• OTH_01 can be used to set timing of servo motor stop. During servo motor operation, setting of "Brake

cmd output speed level" (OTH_02) and "Waiting time for brake signal" (OTH_03) will be followed.

• The servo motor will turn into non-excitation status immediately when an alarm occurs independent of

this setting. At this time, movable parts of the machine may move due to its own weight or external force

before brake operation.

■ Electromagnetic brake operation when servo motor rotates

After an alarm occurs during servo motor rotation, the servo motor will perform stop operation, and the

"Electromagnetic brake timing (BRAKE)" output will be OFF.

After "Brake cmd output speed level" (OTH_02)/"Waiting time for brake signal" (OTH_03) are set, timing of the

"Electromagnetic brake timing (BRAKE)" output can be set.

Even if the set value exceeds max. speed of the servo motor, the max. speed will still be the upper limit.

When "*Servo OFF or G1 alarm stop mode" (ALM_01) and "*G2 alarm stop mode" (ALM_02)" is "Stop by

command speed 0", electromagnetic brake operation will be performed according to OTH_01 after the motor is

stopped by command.

● Condition for electromagnetic brake operation when servo motor rotates

When any of the following conditions is

satisfied, the brake willl operate.

• After the motor is OFF, the motor speed is

below the set value of OTH_02.

• After the motor is OFF, and the motor rotates

for the set time of OTH_03.
