DC590+ DRV Series DC Digital Drive
This AH500935U001 board continues to support both AC and DC analog tachos with a calibration range of 10 to 200V.
• For AC tacho feedback, use terminals G1 & G2, with selector switch in the AC position (left). Calibrate the switches for √2 x full-
speed voltage required, i.e. √2 x 90V = 127V. This adjusts the r.m.s. value received from an AC tacho into the required peak value.
• For DC tacho feedback, use terminals G3 & G4, with selector switch in the DC position (right).
NOTE Do not set the calibration volts to greater than 200V, the max. terminal block rating.
Wire-ended Electrical Encoders (E1, E2, E3, E4, E5, E6)
The wire-ended encoder can be connected to the drive via the Wire-Ended Encoder Option Board. This
board provides terminals E1 to E6. Terminals E1 (0V) and E2 (+24V dc) are the return and supply
respectively.
The drive can accept a standard, 4-channel, quadrature complimentary, wire-ended electrical encoder signal
as speed feedback.
Four feedback boards are available, each having a different supply voltage rating. Complimentary line
driver encoders are recommended.
When using a wire-ended electrical encoder as feedback, be sure to use three channel, twisted, shielded
cable and to ground the shield at the drive end only. Belden 8777 cable is recommended.
The speed loop is set-up for the Encoder by the SPEED FBK SELECT parameter in the SPEED LOOP
function block. Select ENCODER for this parameter.
The maximum allowable encoder frequency is 100kHz, thus with a standard 1000 lines per revolution
encoder the motor speed cannot exceed 6000 rpm.
For specification and connection information refer to Parker SSD Drives or the Technical Manual supplied with the Encoder.
