Microstep setting
The microsteps of the driver are set by DIP-2 terminal with the
following 16 channels. They are set separately by the first 4 of
the 6 DIP-switch.(The other 2 are for function setting). Details
are as below: Microsteps(pulse/R)

D4 | ON | OFF | ON | OFF | ON | OFF | ON | OFF | ON | OFF | ON | OFF | ON | OFF | ON | OFF |
D5 | ON, Double pulse: PU is Clockwise pulse signal, DR is
counterclockwise pulse signal |
OFF, single pulse: PU is step pulse signal, DR is direction signal |
D6 | Self detect switch (OFF: accept external signal, ON: the driver is
running at 30R/M internal) |
Terminal function
Port | Pin No | Mark | Function | Notes |
DB15 | 1 | PU+(5V) | Step pulse signal+ | It can connect +5V or +24V, but an extra resistor is needed if it
connect +24V |
2 | PU-(5V) | DP5=OFF, PU is pulse signal | Effects on falling edge, the motor goes one step as the pulse input
change from “high” to “low”. Input resistance is 220Ω. Requirement:
low voltage:0-0.5V, high voltage:4-5V, pulse width >2.5μs |
DP5=ON, PU is clockwise pulse signal |
3 | DR+(5V) | Direction control signal+ | It can connect +5V or +24V, but an extra resistor is needed if it
connect +24V |
4 | DR-(5V) | DP5=OFF, DR is direction control signal | Change motor’s direction of rotation. Input resistance is 220Ω.
Requirement: low voltage:0-0.5V, high voltage:4-5V, pulse width
>2.5μs |
DP5=ON, DR is counterclockwise pulse signal |
5 | MF+(5V) | Motor Free signal+ | It can connect +5V or +24V, but an extra resistor is needed if it
connect +24V |
6 | MF-(5V) | Motor Free signal- | Once effects, it will cut off the motor current, the driver stops
working and sets the motor free |
7,8 | NC | NC | NC |
9 | PU+(24V) | Step pulse signal+ | It can connect +24V pulse signal power supply |
10 | PU-(24V) | DP5=OFF, PU is pulse signal | Effects on falling edge, the motor goes one step as the pulse input
change from “high” to “low”. Input resistance is 1.8KΩ.
Requirement: low voltage:0-0.5V, high voltage:24V, pulse width
>2.5μs |
DP5=ON, PU is clockwise pulse signal |
11 | DR+(24V) | Direction control signal+ | It can connect +24V direction signal power supply |
12 | DR-(24V) | DP5=OFF, DR is direction control signal | Change motor’s direction of rotation. Input resistance is 1.8KΩ.
Requirement: low voltage:0-0.5V, high voltage:24V, pulse width
>2.5μs |
DP5=ON, DR is counterclockwise pulse signal |
13 | MF+(24V) | Motor Free signal+ | It can connect +24V motor free signal power supply |
14 | MF-(24V) | Motor Free signal- | Once effects, it will cut off the motor current, the driver stops
working and sets the motor free |
15 | NC | NC | NC |
Motor, power port | 1 | A+ | Connect to the motor |

2 | A- |
3 | B+ |
4 | B- |
5、6 | L、N | Power supply | Power: AC110-220V |
! Caution
1. The input voltage can not exceed AC220V.
2. The input pulse signal effects on falling edge
3. ALM lights and the driver stops working when the driver
temperature is over 75℃. Until the temperature falls to 50℃, it
will restart to work after powered-up. The heat sink is needed when
overheat occurs
4. ALM lights if it is short circuit, please check motor leads and
eliminate other short faults, and then repower up to restore
5. ALM lights if the motor does not connect well with the driver,
please check motor leads and repower up to restore
