Circuit Specifications
| Input Signals | Input Mode | Photocoupler input, Input resistance 220 Ω, Input current 10~20 mA Photocoupler "ON" condition: +4~+5 V, Photocoupler "OFF" condition: 0~+0.5 V |
|---|---|---|
| CW Pulse Signal (Pulse signal) | CW direction operation command pulse signal (when in 1-pulse input mode, operation command pulse signal) Pulse width 5 μs min., rise/fall time 2 μs max., Motor rotates 1 step with pulse fall. (Negative logic pulse input) |
|
| CCW Pulse Signal (Rotation direction signal) | CCW direction operation command pulse signal (when in 1-pulse input mode, rotation direction signal Photocoupler "OFF": CCW, Photocoupler "ON": CW) Pulse width 5 μs min., rise/fall time 2 μs max., Motor rotates 1 step with pulse fall. (Negative logic pulse input) |
|
| All Windings Off Signal | When the photocoupler is "ON," the output current to the motor is turned "OFF," and the motor shaft can be turned by external force. When the photocoupler is "OFF," the operating current set by the "RUN" switch is supplied to the motor. |
|
| Output Signals | Output Mode | Photocoupler and Open-Collector Output (emitter common) External Use Conditions: 24 VDC max., 10 mA max. |
| Excitation Timing Signal | Signal output when the excitation sequence is step "0." (Photocoupler "ON") At Full Step: Output once every 10 pulses. At Half Step: Output once every 20 pulses |
|
| Overheat Signal | Signal outputs when internal temperature of the driver rises to approx. 80 °C or higher. (Automatically resets when the photocoupler is "ON" or OFF below 80 °C.) Automatic all windings off function stops the motor. The output logic of the photocoupler can be switched using the overheat output logic switching setting. |
|
| Function | Automatic current cutback, automatic all windings off, step angle switching, pulse input mode switching, self-inspection function switching, overheat output logic switching |
|
| Indicator (LED) | Power supply input, CW pulse signal input, CCW pulse signal input, output current off signal input, Power supply input, excitation timing signal output, overheat output signal |
|
| Cooling Method (Driver) | Natural cooling method | |

- *4
- T.I.R. (Total Indicator Reading): The total dial gauge reading when the measurement section is rotated once around the reference axis center.
Note
- Do not measure insulation resistance or perform a dielectric strength test while the motor and driver are connected.
Circuit General Specifications
