*: The power supply line for Axis-1 is isolated from Axis-2. Supply the power to each axis.
Important
The pulse is output even while outputting the integrated alarm, but the reliability is low.
For your safety, read out the pulse when the integrated alarm is "LOW level".

Outputs either Up or A phase pulse
Outputs either Down or B phase pulse.
Outputs the synchronous signal when outputting the up/down pulse.
(
The Busy signal doesn't change when outputting the A/B phase
pulse.)
This is the signal ground (0V) for the pulse output signal.
The signal is output when one of the following errors occurs.
- Sensor disconnected error
- Low power error
- In the case of inputting the limit error (LE) of I/O connector
Outputs the low level in the normal operation, and outputs the high
level when an error occurs.
The signal is HIGH level at turning ON the power supply when
"Alarm setting when turning on the power supply" of the function
selector switch is set to "ON: alarm output".
The signal turns ON when the sensor travel exceeds the pulse
output permissible speed.
Outputs the low level in the normal operation, and outputs the high
level when an error occurs.
Outputs when detecting that the sensor is disconnected.
Outputs the low level in the normal operation, and outputs the high
level when an error occurs.
Outputs when detecting low power at the internal converter or
24VDC at the external power supply.
Outputs the LOW level in the normal operation, and outputs the
HGH level when an error occurs.
Connects this signal to 0V of the external power supply for the
output signal.
Inputs the LOW level when clearing an error.
Inputs the LOW level when inputting the limit error signal from
external.
Connects to + side of the external power supply for the input signal.
