M Series two-phase stepper motor driver is based on the sub-type drive PI current control algorithm design low noise low vibration and low heat. Can be selected via DIP switches operating current and subdivision there are 16 subdivision 16 kinds of the current selection with overvoltage undervoltage alarm phase overcurrent protection motor phase open detection the input control signals are optically isolated. Built-in self-running mode you can set up a self-running speed can also be controlled from an external signal to start and stop running and motor reversing. Pulse direction and enable end has a constant current and reverse protection can be directly connected to 4-28V signal level enable end can also be provided as an alarm output. Feature 1. Power supply:18-70V DC 2. Output Current: 16 files DIP switch selection maximum 4.5 amps (peak) 3. Current Control:. PI control algorithm low vibration low noise low heat 4. Subdivision setting: DIP switch settings optionally 16 files 5. System self-test: when drive is powered automatic detection of motor parameters thus the motor current can be optimized algorithms and anti-resonance damping algorithm 6. Control: Support Pulse and direction mode and double-pulse mode 7. Idle current: about 1 second no pulse signal input current automatically reduced by half 8. Self-running: from running by coding switch from continuous operation as well as the controlled self-running can also be subdivided switch from running speed 9. Constant current input: pulse direction and enable terminal has a constant input function can be directly connected to PLC high-voltage input signal without external series resistor buck limit protection 10. Alarm output: via internal jumpers can enable client functionality into alarm output 11. Working Temperature: 0-42 ° C [32 - 106 ° F] 12. Vibration: 5.9m/s2 max
