About This Product
The PG-E3 Option allows the user to connect an ERN1387 rotary encoder for motor speed
feedback to the drive and take advantage of the "Closed Loop Vector for PM Motors"
control mode. The option helps increase the control accuracy and performance.
This encoder signal allows the drive to compensate for subtle variations in the load, while
providing the drive with the necessary data to control the output frequency and maintain an
accurate constant speed.
The PG-E3 Option reads a maximum frequency of 20 kHz. Be sure to select an encoder with
an output of maximum 20kHz when operating at maximum speed.
When using the PG-E3 Option, the drive must be in the "Closed Loop Vector Control for PM
Motors" control mode. Refer to the Technical Manual of the drive for details.
