590D DC Digital Converter - HA467078
Analog Tachogenerator (G1, G2, G3, G4)
Refer to Chapter 13: "Standard and Optional Equipment" -
Optional Equipment for further information.
An Analog Tachogenerator is connected to the Converter using
a screened twisted pair cable throughout its entire length to
provide speed feedback via the Tacho Calibration Option
Board. This provides facility for an AC or DC tachogenerator.
The screen is grounded or earthed only at the drive end, any
other grounding arrangement may cause problems.
Terminals G1 and G2 are for AC tacho connections.
Terminals G3 and G4 are for DC tacho connections.
The speed loop is set-up for an analog tacho by the SPEED
FBK SELECT parameter in the SPEED LOOP function block.
Select ANALOG TACH for this parameter.
If an AC tachogenerator is used the output is rectified to produce the ac feedback to the
speed loop. Consequently, the controller can only be used with a positive setpoint.
Refer to Chapter 4: "Operating the Converter" for set-up information.
Microtach (F1, C1, C9)
Refer to Chapter 13: "Standard and Optional Equipment" - Optional
Equipment for further information.
The Parker SSD Drives MICROTACH is available in two versions:
• 5701 Plastic Fibre Microtach
• 5901 Glass Fibre Microtach
A Microtach can be connected to provide speed feedback via the
Microtach Option Board. using the international standard "ST" fibre
optic system.
F1 is the fibre optic receiver input socket. Terminals C9 (+24V dc) and
C1 (0V) are used to provide the supply and return respectively.
The speed loop is set-up for the Microtach by the SPEED FBK SELECT parameter in the
SPEED LOOP function block. Select ENCODER for this parameter.
Maximum Microtach frequency 50kHz, i.e. with a 1000 lines per revolution Microtach, the
motor speed cannot exceed 3000 rpm.
For specification and connection information refer to Parker SSD Drives or the appropriate
Technical Manual.
Wire-Ended Encoder (G1, G2, G3, G4, G5, G6)
Refer to Chapter 13: "Standard and Optional Equipment"
- Optional Equipment for further information.
• The wire-ended encoder is connected to the Converter
using a screened cable throughout its entire length to
provide speed feedback.
Terminals G1 (0V) and G2 (+24V dc) are the return
and supply respectively.
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.
Maximum Encoder frequency 100kHz, i.e. with a 1000
lines per revolution encoder, the motor speed cannot exceed 6000 rpm.
For specification and connection information refer to Parker SSD Drives or the appropriate
Technical Manual.
