Function description

Power Supply: DC+ ; DC-

Voltage: 24～50DC, normally Linear Power Supply applied(appendix), ripple voltage higher than 50V may damage driver. The output current of LPS shall be 60％more than that of driver. In case of switching power supply(strongly recommended)applied, please pay attention to the current shall meet motor’s current.
Attention: incorrect connection may cause driver damaged.

Speed regulation choice(RV ; AVI)

1.Setup speed by potentiometer (RV).The dipswitch SW2 must be ON status to enable this function. CW rotate the potentiometer will increase speed. CCW- speed down.

2.Setup speed by analog input (AVI). The dipswitch SW2 must be OFF status to enable this function..AVI terminal accept 0～5V voltage or PWM signal from controller.AVI terminal with input resistance of 100K, current consumption≤5mA.

SW2	Command?to	Speed?adjust	Comman	Current
ON	RV	CW—speed?up, CCW—speed?down	－	－
OFF	AVI	0～5V?analog?input	0～5V?volage	≤5mA
OFF	AVI	PWM	1KHz?duty?cycle	－

Only one of above two modes can be used to adjust speed (another mode shall be enabled). Once AVI terminal applied, (RV) potentiometer shall be CCW turned to Min. position.PWM signal are 5V TTL level.

Run/Stop(ENBL)

ENBL terminal is applied to control motor Run/Stop, Common positive terminal is ＋5V.

Optical coupler short circuit make motor run, it open circuit make motor stop.

See below circuit

CW/CCW Rotation(F/R)

?? ?
F/R terminal is applied to shift motor rotate direction, common positive terminal is＋5V.
?? ?
Motor run in CCW when optical coupler is short circuit, motor run in CW when optical coupler is open circuit.
?? ?
Attention:don’t change the connection sequence of phase wires of motor to shift rotate direction.

Motor Brake Command(BRK)

BRK terminal applied to stop rotation quickly. Motor will stop normally within 50ms. But inertia of load can’t exceed 2 times of motor inertia, otherwise brake will cause driver alarm.

Time of acceleration a
