1Introduction

This manual describes the features and hardware specifications of the Motor Sensor Board

(AD-MS/PJ4). The Motor Sensor Board is used with connecting to EB-850/PJ4E, which the 32-bit

single-chip microcomputer V850E2/PJ4-E from Renesas Electronics Corporation is mounted on.

2.1 Resolver 1 I/O Connector (CN12)

This is the connector for excitation signals for resolver and SIN / COS signals for detection

coil.

Excitation signal outputs PWM signals through LPF (this can be set to disable. JP3) and

current AMP. It has variable resistance for level adjusting. Also, at the current AMP, it can

change the feedback adjusting resistance (J3,J4). As the default setting, the resistance is set

to 10kΩ. The feedback adjusting resistance can implement two parallel connections in one

socket.

The adjusting variable resistance (VR1) is a variable resistance of 20KΩ.

The SIN, COS, and excitation signal of the detection coil are adjusted to the input level of the

microcomputer. It is connected to the microcomputer after noise canceling by LPF that is set

to Fc=234kHz for the level conversion and noise canceling purpose.

2.2 Motor Control 1 Connector (CN14)

Motor Control 1 Connector is a connector to output digital signals for six-phase motor. It

connects six digital signals for UVW and one digital signal for gate block. The output is an open

drain output. It pulls up with 1KΩ for internal 5V.

2.3 Analog Input Connector (CN7)

The Analog Input Connector is connected to CPU analog input terminal with adding protection

diode and resistance. The connector itself is not mounted, and it is 2.54pitch through-hole.

To use it for controlling, it has 1 digital input function. For some analog and digital signals, the

connection destination can be changed by JP settings.
