3.2.2 ENA（IN3）port
The default ENA port is the driver offline (enable) function:
When the internal optocoupler is off, the driver outputs current to the motor;
When the internal optocoupler is on, the driver will cut off the current of each phase of the motor to
make the motor free, and the step pulse will not be responded.
When the motor is in an error state, it is automatically turned off. The level logic of the enable signal
can be set to the opposite.
At the same time, this port can be reused as other functions like IN1 and IN2.
3.2.3 ALM（OUT1）port
The driver includes an optically isolated output port ALM. By default, the ALM port is an alarm output
port. When the driver is in an error state and normal operation, the ALM port outputs different
optocoupler levels.
It can also be reused for other functions, as shown below:
3.3 USB port
The USB is a micro usb connector and requires a USB bridge.

4.2 Standby current
SW4 is used to set the current percentage of the driver when it is in standby.
SW4 = ON, as long as the driver is in the enabled state, the current remains at the set current
SW4 = OFF. After the driver stops receiving pulses for a certain time, it enters the standby state,
and the current drops to a certain percentage of the set current.
The default setting is: 1 second after stopping receiving the pulse, the motor winding current will be
50%.
4.3 The setting of pulse per revolution
Set the pulse per revolution required by the motor. Due to digital control, the number of subdivisions
can be set to any number between 200 and 65535.

4.4 Pulse command filtering
The driver has a built-in pulse command smoothing function, which can make the motor start more
stable.
SW9 = ON, enable pulse command filtering
SW9 = OFF, disable pulse command filtering
The default command filter time is 512*61us=31ms
Command filtering can smooth the motor movement, but also introduces lag. The user needs to
choose whether to enable this function according to the actual situation.The filter time can be set by
the debugging software:

6. Phase loss alarm
The driver has a motor phase loss alarm function, which can detect the phase loss state of the
motor during stationary and movement. During the operation of the stepper motor, due to
mechanical reasons, the winding wire of the motor may be loosened and disconnected. At this time,
the driver will output an alarm signal to prevent the device from making an erroneous action.
Since this function relies on the current detection of the motor windings, this function has a false
alarm when the motor current is too small (less than 300 mA). At this point, the user can turn off this
function. In the parameter management and setting interface of the debugging software, set
parameter No. 188(phase loss detection enable) to 0.
7. Internal motion control function
When working in the internal pulse command mode, the PUL and DIR ports are used as IO input signals.
The IO function needs to be set through the debugging software. As shown below:

7.1 Communication control mode
In this mode, the user can make the motor run the specified pulse stroke or jog operation by
communicating the given operation command.
In internal pulse mode, the motor is controlled by register 18
0：Waiting state.
The driver receives any control command and will resume the waiting state after the driver
processes it. So reading this register always returns 0.
1：Fixed length forward rotation.
In the relative position mode, the motor runs in the forward direction according to the 70 ～74
register parameters.
In the absolute position mode, the operation state is determined according to the current position
and the absolute position set by 70～74.
2：Fixed length reverse rotation.
In the relative position mode, the motor runs in the reverse direction based on the 70～74 register
parameters.
In the absolute position mode, the operation state is determined according to the current position
and the absolute position set from 70 ～74.
3：Speed mode, continuous forward rotation.
According to 75 and 76 registers, the motor runs at forward acceleration.
4：Speed mode, continuous reverse.
According to 75 and 76 registers, the motor runs at reverse acceleration.
5：Emergency stop
According to the 77 register, the motor decelerates and stops.
6：Slow down and stop.
In position mode, the motor decelerates and stops according to the 71 register
In speed mode, the motor decelerates and stops according to the 76 register
Others: no effect.
7.1.1 Point control mode
The communication controls the function of the motor to run the specified pulse stroke. The specific
modes and parameters to be set are as follows (register addresses are not specified or specified as
decimal numbers):
(1) Set the value of register address 20 (preset application selection in internal pulse mode) to
0(Communication control, respond to the command of register address 18)

(4) Communication given operation command: start the point movement by writing the values “1”
(fixed length forward rotation) and “2“(fixed length reverse rotation) to register 18.(For details on
this register, please see "Driver Control Mode" Set register 18 in [17~23]";
(5) During operation, if need to stop, please write value “6“(deceleration to stop, deceleration is
the setting value of register 71) and value “5”(emergency stop, deceleration is the setting value
of register 78) to register 18 .
Note:
When the motor is in operation, it only responds to the stop command (deceleration stop or
emergency stop). If it is necessary to change the running direction of the motor by command,
please send the stop command to wait for the motor to stop, and then send the start signal of the
other direction.
The acceleration (register 70), deceleration (register 71), and speed (register 72) are changed
during motor operation, but the driver will not respond to these set values immediately. It will not run
at the set values until the motor is stopped and restarted.
It is important to note that the emergency stop deceleration (Register 78) is responded to during the
current sport emergency stop, without waiting for the next stop of the emergency stop.
7.1.2 Jog control mode
3R110Plus has the function of controlling the jog operation of the motor through communication.The
specific modes and parameters to be set are as follows (register addresses are not specified or
specified as decimal numbers):
(1) Set the value of register address 20 (preset application selection in internal pulse mode) to
0(Communication control, respond to the command of register address 18)
(2) Set the function of the digital input and output port according to the application requirements and
the actual wiring terminals;

please see "Drive Control Mode" Set register 18 in [17~23]";
(5) During operation, if need to stop, please write value “6 “(deceleration to stop, deceleration is the
setting value of register 76) and value “5” (emergency stop, deceleration is the setting value of
register 78) to register 18 .
Note:
When the motor is in operation, it only responds to the stop command (deceleration stop or
emergency stop). If it is necessary to change the running direction of the motor by command,
please send the stop command to wait for the motor to stop, and then send the start signal of the
other direction.
The acceleration (register 75) and deceleration (register 76) are changed during motor operation,
but the driver will not respond to these set values immediately. It will not run at the set values until
the motor is stopped and restarted.
It is important to note that the emergency stop deceleration (Register 78) is responded to during the
current sport emergency stop, without waiting for the next stop of the emergency stop.
The speed (register 77) can be changed during the operation of the motor, and the driver will
respond immediately, that is, the motor will run at the set speed value immediately, without stopping
and restarting to respond.
7.2 IO Control: Start and Stop + Direction
With this mode, two IN terminals are used to control the operation of the motor. One IN terminals is
used to control the start/stop of the motor, and the other IN terminal is used to control the running
direction of the motor. The specific settings are as follows:
(1)Command mode: 0 - internal pulse mode
(2)Internal application mode: 2 –IO speed control: start and stop + direction
