3) Control signal port
Name | Explanation |
PUL＋ | Pulse input signal: pulse effective edge adjustable, the default pulse rising edge is valid; in order to reliably respond to the pulse signal, the pulse width should be greater than 1.2μs. Such as the use of +12 V or +24 V when the need to string 3K resistance |
PUL－ | |
DIR＋ | Direction input signal: high / low level signal, in order to ensure reliable reversing of the motor, the direction of the signal should be preceded by pulse signal at least 5μs to establish, such as the use of +12 V or +24 V string 3K resistor. |
DIR－ | |
ENA＋ | Enable control signal: This input signal is used to enable or disable. When ENA +, ENA- have input, the drive will cut off the motor phase to make the motor in a free state. When this function is not required, the terminal can be left floating. |
ENA－ | |
Pend+ | Positioning completion signal positive side |
Pend- | Positioning completion signal negative |
ALM＋ | Alarm output positive terminal |
ALM－ | Alarm output negative terminal |
