7.2 Speed control mode

This mode allows for accurate, smooth control of the rotation speed and direction of the servo motor.
* To set [PC**], set parameter write restriction [PA19] to "00E".

7.2.1 Speed Control Mode Operation Instruction

The servo motor will rotate when signal ST1 and ST2 turn on. An operation example of the speed control mode is
shown below.

Internal speed command settings

Speed command and speed

The servo motor operates at the speed set in parameters.

Up to 8 speeds can be set to the internal speed command.

The following table indicates the rotation direction according to forward rotation start (ST1) and reverse rotation

start (ST2) combination.

2. If the torque limit is canceled during servo lock, the servo

motor may suddenly rotate according to position deviation in

respect to the command position.

Connect the wirings as follows when operating in forward or reverse rotation with the internal speed command set

to the eighth speed.

Note that the inputs are configured as Current sink NPN Type
