MF+
Connected to the signal power supply, +5~+24V can be driven
MF-
When it is active
（
low level
）
, the motor coil current is turned off, the driver stops
working, and the motor is in a free state.
Pend+
When the drive has finished a given pulse, the in-position signal is valid (output
optocoupler is on). Pend+ is connected to the pull-up resistor to the positive
terminal of the output power supply. The maximum current is 50mA.
Pend-
Pend- is connected to the negative terminal of the output power supply.
ALM+
When overcurrent, overvoltage, undervoltage or position error alarm, the alarm
signal is valid (output optocoupler is on). ALM+ is connected to the pull-up
resistor to the positive terminal of the output power supply. The maximum drive
current is 50mA.
ALM-
ALM- is connected to the negative terminal of the output power supply.
PWR
Power Indicator. Power on, green light is always on
ALM
Fault indicator.
Flash once: overcurrent or phase-to-phase short circuit;
Flashing twice: over voltage;
Flashing three times: under voltage;
Flashing five times:following position error

4 Wiring
The CL57Y
、
CL86Y can accept differential and single-ended inputs (including open-collector and PNP
output). The CL57Y
、
CL86Y has 4
、
5 optically isolated logic inputs which are located on connector P1 to
accept line drive control signals. These inputs are isolated to minimize or eliminate electrical noises
coupled with the drive control signals. Recommend using line drive control signals to increase noise
immunity for the drive in interference environments.
A complete closed loop stepper system should include a closed loop motor, a drive, a power supply
and a controller (pulse generator). The typical connection is shown as figure 3.
