The Parker SSD Drives MICROTACH is available in two versions:
z 5701 Plastic Fibre Microtach z 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. If fitted, terminals C9 (+24V dc) and C1 (0V) can be used to provide the supply and return
respectively.
NOTE 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.
The maximum Microtach frequency is 50kHz, thus with a standard 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.
NOTE This 590C product is not compatible with the older style of Microtach Speed Feedback option (AH058654U001, with 4-
way terminals).

Refer to Chapter 3: “Installing the Drive” - Optional Equipment for further information.
The wire-ended encoder is connected to the Drive using a screened cable throughout its entire length to provide speed feedback.
Terminals E1 (0V) and E2 (+24V dc) are the return and supply respectively.
NOTE 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 appropriate Technical Manual.
