Port and Wiring

Port signal description

ALM, SPEED, and PLC Wiring

The internal structure of ALM and SPEED of this drive is as follows, which is related to the PLC wiring and the type of PLC input. For example, input modules such as AX40/741/42/50/60 of Mitsubishi A series PLC and QX40/41/42 of Q series only support source mode, and users should connect according to the characteristics of this input type.

Output interface circuit of brushless driver

SPEED port description

The speed port reflects the rotate speed of motor by frequency output, 1000rpm = 1000 Hz ,500rpm = 500 Hz. Note that correct feedback of this port depends on the correct setting of pole numbers. It can be correctly reflecting the rotate speed of motor under close loop control; the default setting of open loop is 4 poles motor rotate speed feedback and bottom setting which can’t be changed by customer

Speed regulation

BLDH-300R has 5 speed regulation ways as following:

1. Via built-in potentiometer

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

2. Via external potentiometer

Use a potentiometer with a suitable resistance value . The motor speed can be adjusted mannually. Please note that RV should be rotated anticlockwise to limit position.

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).

4.PWM

When using PWM speed regulation, the built-in potentiometer RV must be OFF. Below chart shows the relationship between motor speed and duty ratio.

5.RS485

This drive has 2 kinds of interfaces for rs485 communication wiring, one is RJ45, the other is pluggable terminal

The “2-wire” electrical interface in EIA / tia-485 standard is adopted in the BLD300R. RJ45 interface has A、B、 GND pin. Take the Section 7.3.2 in GB / T 19582.2-2008 for detail reference. The pluggable terminalis is just for users to debug programe. Considering the industry practice, there’s 3.3V voltage on the RJ45Plug, Users can decide whether to connect 3.3V or not according to the actual situation.
