Control Signal
Symbol Name
ENBL- Offline enable signal input
ENBL+ Offline enable signal input
DIR- Direction signal
Overview
DIR+ Direction signal
Subdivision setting (within 200~12800)
PUL- Pulse signal
Current setting (within 0.1~3A), resolution: 1
PUL+ Pulse signal
Can drive 4-wire, 6-wire and 8-wire motors
With overvoltage, undervoltage, overcurrent, and phase-to-phase short circuit
protection functions
When the offline enable signal is active, the drive fault is reset, any valid
Signal input: single-ended pulse/direction
pulses are disabled, the output power component of the drive is turned
Variable current control greatly reduces motor heating
off, and the motor has no holding torque.
Impulse response frequency up to 500K (factory default 160KHz)
Signal voltage 5~24V compatible
Motor and power
Symbol Name Remark
The connection between the driver and the two-phase hybrid stepping
B- Phase B-
motor is four-wire. The motor windings are connected in parallel and in
B+ Phase B+
series, and the connection method is good. The high-speed performance
A- Phase A-
is good, but the driver current is large (1.73 times the motor winding
A+ Phase A+
current). The drive current is equal to the motor winding current.
GND Input Power- 0V
VCC Input Power + +12~32V
