● Upon detection of the step-out and OFF the
coupler output of the alarm signal. The ALM LED flashes.
(0.5-second intervals)
● During the alarm signal output is, it makes the motor in HOLD state.
Drive pulse will not be accepted.
(6) Alarm clear signal input (ACLR）
① Operating current range : 2.6mA～19.5mA
The photo-coupler turns on with
inter-terminal voltage of 4.5 V～26.4 V.
(Photo-coupler diode V
F
≒ 1.1 V)
● When you enter the alarm clear signal to shut off the excitation current
of the motor, and returns the internal process for the step-out to the
initial state.
● When you release the input of the alarm clear signal, it will be canceled
the alarm output signal. (Photo-coupler ON), and I will output the
excitation current to the motor.
