Setting STOP current
Zero point excitation output signal(ZERO OUT)
RUN current is phase current for 5 phase stepping motor.
There can be an error in RUN current setting value by driving frequency.
RUN current should be used within the rated current of motor, or it may cause overheating,
step-out and loss of torque.
STOP current is phase current provided to 5-phase of stepping motor to be stopped.
The switch setting value of STOP current is a percentage of RUN current switch setting current
value.
There can be an error in STOP current by coil impedance of motor.
This function shall be operated when CURRENT DOWN switch is set to OFF. In case CURRENT
DOWN switch is set to ON, RUN CURRENT shall be provided both when a motor stops and
when a motor runs.
It indicates the initial step of excitation status of stepping motor and rotation position of motor
axis from previously set zero.
HOLD OFF function
HOLD OFF is [H], the excitation is released, because current provided to each phase is cut off.
HOLD OFF is [L], the excitation is in a normal status.
It rotates motor axis by external force or is used for manual positioning.
Input H/L means ON/OFF of photocoupler in a circuit.

Overheat
Overcurrent
It drives a motor dividing basic step angle(0.72°) by setting value of resolution.
※
Selectable resolution(Selectable Step angle)
Change into the resolution in MS1/MS2 by DIVISION SELECTION input.
Motor is rotated by resolution in MS1 when DIVISION SELECTION signal is [L] and MS2 for [H].
Change the resolution after motor is stopped or, it may cause a step-out of motor.
Input H/L means ON/OFF of photocoupler in a circuit.

※
When base temperature of driver is over 80
℃
, alarm LED(Red) is lighted and motor will be stop
holding the excitation. Reset the power after remove the existing factors of overheat that can
be occurred to release the Alarm.
When overcurrent is applied from breakdown or error to the motor, alarm LED (Red) is Flickered.
In case overcurrent occurs, a motor will become HOLD OFF. A driver will resume its normal
operation when error causing factors are disappeared.
When resolution is changed during the operation of motor, it may cause a step-out of motor.

※
It may cause malfunction if above instructions are not followed.
1. If motor does not rotate
①
Check the connection status of controller and driver and pulse input specification. (Voltage,
width)
②
Check the input pulse method and connected method is same.
③
Check pulse and direction signal is connected correctly for 1 pulse input method.
3. If motor does not work properly
①
Check the connection of driver and motor.
②
Check the pulse input specification of driver. (Voltage, width)
③
Check output current for current adjuster and current for motor operation as correct.
④
After turning off the power, wait at least 15 seconds before turning the power back on.
2. If motor rotates as a reverse direction
①
Check input pulse connection of CW and CCW is correct for 2 pulse input method.
②
In case of 1-pulse method, it is forward rotation when CCW input is [H] and reverse rotation
when CCW input is [L].
ZERO OUT means the initial status of motor excitation (STEP 0), it outputs per 7.2° of rotation
in Full Step. (It outputs 50times per 1 rotation of motor.)
Ex) Full step : It outputs one time when input 10 pulse.
20 division : It outputs one time when input 200 pulse.
※
Pulse input method selection
1 Pulse method : Input pulse signal input in CW and rotating direction signal in CCW.
It rotates to CCW when [L] and CW for [H].
2 Pulse method : Motor is rotated to CW when input pulse in CW and to CCW when input
pulse in CCW.

4. Caution for installation
①
②
Excessive heat generation may occur on Driver. Keep the heat sink under 80
℃
when installing
the unit.(In case it is over 80
℃
, forcible cooling shall be required.)
In order to increase heat protection efficiency, keep the heat sink as close as possible to
metal panel and keep it well-ventilated.
5. Caution for using function switches
6. Installation environment
①
Check the position of self-diagnosis switch before turn on the power.
It may be dangerous if turn on the power in [ON] status, due to motor is worked instantly or
cause a malfunction.
②
When the selection switch of input signal method is changed to 2 Pulse input method during
the operation with 1 Pulse input method, it may be danger as the revolution way of the motor
is changed conversely.
Please do not change the input signal method during the operation.
1. Caution for signal input
①
Do not input CW, CCW signal at the same time in 2 Pulse input method. It may not work
properly if another signal is supplied when one of them is ON.
②
In case, the signal input supply is higher than rated supply expressed on the specification,
please connect the additional resistor to external part.
2. Caution for supplying power
①
Use the power enough to supply the run current when turn on the power.
②
The current value indicated on power supply is the max. input of driver.
