EN
If EN and GNDE connect, the motor runs;
If EN and GNDE disconnect, the motor stops. (They disconnect
by default.)
F/R
If F/ and GNDE connect, the motor runs anti-clockwise
If F/ and GNDE disconnect, the motor runs clockwise
GNDE
Control signal common ground port
BRK
Under port control mode P-03-4, BRK connects with GNDE, the
motor brake stops
Output signals
SPD
Frequency output.
The relationship between the frequency detected and the speed is:
N(rpm)= F
F: Output pulse frequency(Hz）N: Motor speed
For example：F=500Hz, then N(rpm)=500
(Note: Motor poles should be set right)
ALM
It is a high resistance output, and when a fault occurs, it outputs a
low level

Brushless Motor Driver SEH400RB
The external potentiometer SV input wiring is shown below：
The external analog SV input wiring is shown below:
4.4 Output circuit description
ALM and SPD terminals as below, its connection mode with PLC is related to the type of PLC input
terminal.

setting
1. External analog speed regulation
2. Key speed regulation or 485 speed regulation
Speed setting
Step size is 100RPM; The set speed is lower than (400rpm/ pole
pairs) and the motor does not rotate；
Direction setting
0. Motor stops；
1.Enter the relevant menu through the panel key to set the forward
rotation；
2.Enter the relevant menu through the panel keys, and set the reversal
3.Motor brakes；
4.Direction port control.(F/R, EN）
Reduction ratio setting
Set the speed ratio of the reducer；
Alarm reset
Display the alarm code and press SET to reset the alarm
Polar number setting
Set the pole pairs of the adaptive motor (It is not recommended to
change the pole pairs during motor operation)；
Under speed time setting
Set the under speed time. (E.g, set it as 5s, when the speed of the
motor is less than 50% of the set speed for over 5s, the motor will
stall.)
Maximum speed setting
Set the upper limit of the speed (it is recommended to set it to the
maximum speed of the motor)；
Acceleration and
deceleration time setting
Set the ACC and DEC time through the panel keys；
485 communication
address control
Select and control 485 communication address in steps of 1；
485 communication rate
setting
Set the 485 communication rate in steps of 1；
Port indication
Indicates the status of each IO port, read-only；
Data initialization
Restore the operation data to the factory setting；

6.Function setting of external control port.
6.1 Start and stop
EN and GNDE are disconnect by default, When the power is turned on, the
motor will not rotate. There are two ways to start the motor:
1. Press START to start and STOP to stop the motor.
2. Connect EN and GNDE. A switch or PLC can be added between EN and
GNDE to control the motor start and stop. See right.
6.2 Direction control.
Here are two methods to control the direction.
1. Through the panel MODE->P-03.
2. Disconnect F/R and GNDE, motor runs clockwise.
Connect F/R and GNDE, motor runs anti-clockwise.
6.3 Speed regulation mode.
6.3.1. Knob speed regulation.(Default method.)
6.3.2 MODE->P-01->SET->2 to select speed regulation with keys, press page up or page down to select
request speed.
6.3.3 In addition to using the built-in potentiometer knob on the panel for speed regulation, the external
port SV can be used for the following settings for speed regulation. To start, set MODE->P-01->SET->1.
