DCLON: Transistor turns ON while the motor is decelerating. However, the

 

 

 

 

signal is not output when the motor has stopped because the deceleration

When an operation command has been started by the strobe signal input

 

 

 

 

(STB), the motor operation status output remains OFF until the strobe

 

 

 

 

signal input is set to the opened condition.

When an operation has been aborted because of servo OFF,

 

 

 

 

instantaneous stop or deceleration stop, the last status is held as the
