The pin No. to connect is the same for VDC and VDC. Output Signal Connection Keep the output signal voltage and current below VDC and m respectively. Power Supply Use a power supply that can supply sufficient input current. When power supply capacity is insufficient, a decrease in motor output can cause the following malfunctions: does not operate properly at high-speed. Slow motor startup and stopping. Notes on Wiring Use twisted-pair wires of WG and keep wiring as short as possible [within m (. ft.)]. Note that as the length of the pulse signal line increases, the maximum transmission frequency decreases. Technical reference Page F- Use wires of WG or thicker for motor lines (when extended), power supply lines and protective earth line. To ground the driver, lead the ground conductor from the protective earth terminal (M) and connect the ground conductor to provide a common ground point. Signal lines should be kept at least cm (.9 in.) away from power lines (power supply lines and motor lines). Do not bind the signal lines and power lines together. If noise generated by the motor cable or power cable becomes a problem due to the wiring and layout, shield the cables or use ferrite cores. Incorrect connection of DC power input will lead to driver damage. Make sure that the polarity is correct before turning power on.

CW Pulse duty: % and below The shaded area indicates when the photocoupler diode is. The motor moves when the photocoupler state changes from to. The minimum interval time when changing rotation direction is μs. This value varies greatly depending on the motor type, pulse frequency and load inertia. Pulse Signal Characteristics Keep the pulse signal at the "photocoupler " state when no pulses are being input. Leave the pulse signal at rest ("photocoupler ") when changing rotation directions. ll Windings Off (WO), Step ngle Select (CS) Input Signal Input Circuit and Sample Connection Controller + V Open-Collector Output kω + V, m ll Windings Off (WO) Input Signal Inputting this signal puts the motor in a non-excitation (free) state. This signal is used when turning the motor by external force or manual home position is desired. The photocoupler must be "" when operating the motor. ll Windings Off Input Signal Current Holding Torque Release The shaded area indicates that the motor provides holding torque in proportion to standstill current set by motor stop current switch. Switching the "ll Windings Off" signal from "photocoupler " to "photocoupler " does not alter the excitation sequence. When the motor shaft is manually adjusted with the "ll Windings Off" signal input, the shaft will shift up to ±. from the position set after the "ll Windings Off" signal is released. Step ngle Select (CS) Input Signal When this signal input is "," the motor will operate at the basic step angle regardless of the settings of the step angle setting switches. When the signal input is "," the motor will operate at the step angle set with the step angle setting switch. To change the step angle, do so when the "Excitation Timing" signal output is "" and the motor is at standstill.

Current Cutback (CD) Output Signal When the automatic current cutback function is activated, the "Current Cutback" output turns on. larm (LM) Output Signal Protective Function larm LRM LED Normal Fault Normal Run Light Stop When the motor is running, if the driver overheat, overvoltage, or overcurrent protective function is detected, the "larm" output turns off, and the LRM LED of the driver flashes. The current to the motor is also cut off to stop the motor. You can count the number of times the LRM LED flashes to confirm which protective function is activated. This signal normally stays on, but turns off when a protective function is activated. Run Excitation Timing (TIM) Output Signal The "Excitation Timing" signal is output to indicate when the motor excitation is in the initial stage (step "" at power up). The "Excitation Timing" signal is output simultaneously with a pulse input each time the excitation sequence returns to step "." The excitation sequence will complete one cycle for every. rotation of the motor output shaft. s/step : Signal is output once every pulses. s/step : Signal is output once every pulses. Timing chart at./step (s/step ) When connected as shown in the sample connection, the signal will be "photocoupler " at step "." Pulse Input 9 Rotation Direction Input Excitation Timing Output (Step) Notes: When power is turned, the excitation sequence is reset to step "" and the "Excitation Timing" signal is output. When operating the motor using the "Excitation Timing" signal output, make sure the motor output shaft stops at an integral multiple of..

The minimum switching time to change direction μs is shown as the response time of the circuit. The motor may need more time than that. Depends on load inertia, load torque, and starting frequency. Never input a pulse signal immediately after switching the "ll Windings Off" signal to the "photocoupler " state. The motor may not start. To cycle the power, turn off the power and then wait for at least five seconds after the POWER LED has turned off.
