MEHR 22
Encoder

Description

The MEHR 22 is a optical magnetic incremental encoder; he is a reliable hollow shaft encoder and can be fixed in a different sizes of electric motor.
This encoder is developed for brushless motor, motor feedback and the rotazional speed control.

The encoder MEHR 22 is a real time system for speed and position application.
This encoder provide two square wave outputs in quadrature (A-B 90° degrees) for the direction and counting information and a third channel with lap pulse (zero mark).

Additional there is a magnetic encoder integrated which provide UVW signal as commutation. The resolution of encoder is determined by the number of cycles for revolution (CPR).
Power supply and signals are provided by a 11 pin JAE connector.

Main specifications:

• Output channels encoder: A-B-I and /A-/B-/I
• Optional channels hall sensor: U-V-W and /U-/V-/W
• Output type: Line Driver/TTL/RS-422
• Resolution encoder: 2000 CPR (Cycles Per Revolution)
• Resolution hall sensor: 8 pole
• Frequency: 400kHz short cable (<1m), typical 180kHz @2.000cpr -> 5.400 min-1
• Power supply: 5 VDC
• Small size: 39.0 mm (diameter) x 20.1 mm (lenght)
• Operating temperature: -40°C to +100°C
• Compliant EU-directive 2011/65/65/EU and 2015/863/EU

HREA 48
Encoder

Description

HREA 48 is an encoder optical hall sensor with hollow shaft.

This encoder is specially developed to have a low cost and to work for AGV applications, where precision and speed are essential.

The encoder provide two square wave outputs A and B and their negative outputs /A-/B, The signal I and his negative /I represent the “ZERO” notch, the use of the hall sensors with 8 pole U-V-W and it’s negative /U-/V-/W allows a high precision and control.

Power supply and signals are provided by the braided cable 14Pin 100cm.

Main specifications:

• Output channels encoder: A-B-I and /A-/B-/I
• Optional channels hall sensor: U-V-W and /U-/V-/W
• Output type: Line Driver/TTL/RS-422
• Resolution encoder: 2000 CPR (Cycles Per Revolution)
• Resolution hall sensor: 8 pole
• Frequency: 300 Khz
• Power supply: 5 VDC
• Small size: 48,0 mm (diameter) x 37,0mm (lenght)
• Operating temperature: -40 °C to +85 °C.
• Compliant EU-directive 2011/65/65/EU and 2015/863/EU

Summary

BLD60 Digital BLDC motor driver is a closed-loop speed controller, which uses IGBT and MOS power, uses the Hall signal of the DC brushless motor to perform double-loop speed control, and has a PID speed regulator in the control link. The system control is stable and reliable.

It can always reach the maximum torque at low speed, and the speed control range is 150 to 4000rpm. The driver use the protocol Modbus RS485 RTU to comunicate in a network.

Features:

• PID speed, current double loop regulator
• 20KHZ chopper frequency
• Electrical stop to ensure the quickly action
• Fault alarm function with Over voltage, Under voltage, Over current, Over temperature, and Hall signal illegal.

Summary

The BLD60 DIGITAL PLUS servo drives is a fully digital drives operate in torque, velocity, or position mode and employ Space Vector Modulation (SVM), which results in higher bus voltage utilization and reduced heat dissipation compared to traditional PWM. The drive can be configured for a variety of external command signals. Commands can also be configured using the drive’s built-in Motion Engine, an internal motion controller used with distributed motion applications. In addition to motor control, these drives feature dedicated and programmable digital and analog inputs and outputs to enhance interfacing with external controllers and devices.

Network communication is accomplished using either RS-485/232 or Modbus RTU.
