Encoder Feedback

[Encoder Counts]

Displays the scaled encoder count value. The value is
incremented in the forward direction and decremented in
the reverse direction. Requires a quadrature (dual
channel) encoder and a value in [Enc Count Scale].

After 200ms of encoder loss, a
warning will be issued.

“Enable” 1

After 200ms of encoder loss, an
alarm and an F60 fault will be
issued.

[Encoder Freq]

Not available.

[Max Enc Counts]

Sets the trip point for the “Enc Cnt Max” alarm. The alarm
is high (1) when [Encoder Counts] has exceeded [Max Enc
Counts].

ATTENTION: To guard against possible machine damage and/or personal
injury, be aware that the maximum encoder count value in either direction is

±

32767. If the scale factor or number of pulses exceed this value, the [Encoder

Counts] parameter will roll-over from maximum positive to maximum negative
(or maximum negative to maximum positive). This roll-over must be considered
in applications that use this value.
