Output signal connection diagram

The internal structure of ALM and SPEED ports is following as below, the connection with PLC depends on the input terminal type. For example, if the PLC input module AX40/741/42/50/60 and QX40/41/42 of Mitsubishi only support Sourcing Input, users should connect according to the characteristics of this input type.

Speed regulation

BldH-1500R have speed control methods as following.

1 Via built-in potentiometer

Motor speed is changed when RV knobs is rotated , when anticlockwise, motor speed decreases. If user use other speed modes, RV should be rotated anticlockwise to limit position.

2 Via external potentiometer

Use a suitable potentiometer with a resistance value of 10kΩ; When connect external potentiometer, the middle terminal connects to SV, the other two terminals connect to +5V and GND
① RV should be rotated anticlockwise to limit position.
② Notice the connection sequence of the potentiometer.

3 Via external analog signal 0-5V

When use external analog signal, the built-in potentiometer RV must be OFF (RV should be rotated anticlockwise to limit position).
External analog speed control linearity test curve as below

4 Speed setting via pulse frequency

the motor speed is changed as the variation of pulse of frequency.

5 BLDC PWM control

PWM signal is recommended low level 0V to high level 5V, frequency 3kHz (recommended range 3K ~ 15K Hz). The recommended speed range is duty ratio 5%-96%. The following is a measured example.

6 Communication signal RS485

The communication function of the driver adopts Modbus protocol and conforms to the national standard GB / T 19582.1-2008. The two-wire serial link communication based on RS485 is used. The physical interface adopts RJ45. Three wires need to be connected:,B, A and GND (wiring is prohibited for other terminals in this RJ45 interface). The communication address is set through communication. The 120 Ω terminal matches the resistance and needs to be externally connected by the user.
