Note:
(1) Please refer to “optically isolated input interface” section for details.
(2) Input is considered high level if this terminal is not connected.
(3) Low-level pulse duration should > 8μs. Maximum pulse frequency is 50 KHz.
(4) An active low-level input shuts down power supply to the motor. High-level input or left open makes the Driver fully working. When awaken from shutdown mode, wait 1 millisecond before sending pulse.
|
Note: To avoid damaging, make sure the phase winds are connected correctly. Resistance between leads of different phases is usually > 100KW. Resistance between leads of the same phase is usually < 100W.
