STEP+
In step&direction mode, this input represents pulse signal, each falling edge
active; 5-28V when PUL-HIGH, 0-0.5V when PUL-LOW. In CW&CCW mode ,this
input represents clockwise (CW) pulse，For reliable response, pulse width should
be longer than 1.5μs.
STEP-
DIR+
In step&direction mode, this signal has low/high voltage levels,representing two
directions of motor rotation; In CW&CCW mode, this signal is counter-clock (CCW)
pulse，For reliable motion response, DIR signal should be ahead of PUL signal by
5μs at least. 5-24V when DIR-HIGH,0-0.5V when DIR-LOW.
DIR-
EN+
The EN input enables or disables the drive amplifier. It is an optically isolated input
that accepts a 5 to 24 volt single-ended or differential signal. The maximum
voltage that can be applied to the input is 28V.
When EN input is closed, the drive amplifier is deactivated, all the MOSFETs will
shut down, and the motor will be free. When EN input is open, the drive is
activated.
When the drive has encountered an error and the fault is removed from system, a
falling signal into the EN input will reset the error status and activate the drive
amplifier again.

5. Switch Selection
The SS5 drive uses an 8-bit DIP switch to set the subdivision accuracy, dynamic current, self-test function and pulse mode selection. The detailed
description is as follows:
Running Current
After the drive is matched with the motor model, the running current dialing can set the actual output current to be 40%~100% of the rated current
of the motor.

Self Test
Setting switch SW3 to ON after the drive is powered up will cause the drive to perform a self test move of 2 revolutions both CW and CCW at 3rps.
Setting switch SW9 to OFF disables this feature.
Control Mode
SW4 can set the mode of the control signal. When SW4 is OFF, the host computer needs to provide a pulse signal with one direction signal. When
SW10 is ON, two pulses can be used to control the forward and reverse rotation of the motor. At this time, the pulse input to the STEP terminal
controls the movement of the motor in the CW direction, and the pulse input to the DIR controls the movement of the motor in the CCW direction.
6. Auto Tunning
The Auto Tunning button is used to match the motor to the drive. Under normal circumstances, the motor and the drive have been matched
one-to-one, and the customer does not need to match the motor and the drive.

7. Status Indicator
The green LED is the enable indicator. When the motor is enabled, the LED is always on; when the motor is not enabled, the LED is blinking. The red
LED is a fault indicator. When a fault occurs, the indicator flashes in a cycle; when the fault is cleared by the user, the red LED is always off. The
number of red LED flashes represents different fault information, as shown in the following table:

8. Mechanical Outline
* The amplifiers in the drive generate heat. To operate the drive continuously at maximum power forced air cooling, as from a fan, should be
provided.Never use the drive in a space where there is no air flow or where other devices can cause the surrounding air to be more than 40 °C.
Never put the drive where it can get wet or where metal particles can fall into it.

9. Safety Precautions
The precautions described below are intended to prevent the occurrence of danger or injury to users and other personnel and to use the product
correctly. Please read and understand these precautions thoroughly before using this product.
If the drive is accidentally damaged during operation, the company is only responsible for the repair and replacement of the drive within the
warranty.
The company does not bear the loss of control or casualties and property damage caused by accidental damage to the drive.
Do not use the product with flammable materials when exposed to explosive, flammable, corrosive gases or water splashes or in a nearby
location. Doing so may result in fire, electric shock or personal injury.
Only qualified personnel should be allowed to install, connect, operate and perform inspection/exclusion of product failures. Handling of
unqualified personnel may result in fire, electric shock, personal injury or equipment damage.
Do not move, install, connect, or inspect the product while the drive is powered, and turn off the power when performing these operations.
Failure to follow these instructions may result in electric shock.
Do not use non-electromagnetic brakes in vertical applications. If the drive's protection function is activated, the motor may not stop and the
moving parts of the device may fall, resulting in personal injury or equipment damage.
Always keep the drive's power supply voltage below the rated value. Failure to do so may result in fire or damage to the drive.
Always turn off the power before performing maintenance/inspection. Failure to do so may result in electric shock.
Do not touch the connection terminals on the drive immediately after turning off the power (within 30 seconds, or until the power LED is
turned off). Residual voltage may cause electric shock.
Regularly check the dust accumulated in the open part of the cleaning drive. Accumulated dust can cause a fire.
Do not disassemble or repair the motor and drive. Doing so may result in electric
