Installation
Encoder Status LED's
The MICROMASTER Encoder Module has three LED's, which indicate
current operating status of the encoder module (see Figure 3-4 below).
The LED's have been designed to indicate a healthy or fault condition in
the following areas:
Channel A
Channel B
Zero Pulse
If the Encoder Module is working correctly the LED's will flash on and off
as the shaft encoder is rotated. If a fault condition exists the LED's will
either stop flashing and remain on or remain off.
NOTE
At high motor speeds the LED's appear permanently on – this is due to the
high pulse rates.
Encoder DIP Switches
The DIP switches on the Encoder Module are provided to allow the user to
select the correct settings for the encoder unit attached to the Encoder
Module. See Figure 3-5 below.
The settings of the DIP switches are explained in Table 3-2 below.
