The encoder supply voltage present on the drive encoder connector is
defined by this parameter as 0 (5V), 1 (8V), 2 (15V) or 3 (24V)
The following encoders can be connected to the drive encoder port.
0, Ab
: Quadrature incremental encoder, with or without marker pulse.
1, Fd
: Incremental encoder with frequency and direction outputs, with or
without marker pulse.
2, Fr
: Incremental encoder with forward and reverse outputs, with or
without marker pulse.
The terminations may be enabled/disabled by this parameter as follows:
Provided the set-up parameters for the drive encoder are correct this
parameter shows the encoder speed in rpm.
It should be noted that the value shown by this parameter is measured
over a 16 ms sliding window period (in the same way as
di05
(Pr
0.40,
3.02
)), and so the ripple in this parameter accessible via comms or by an
option module is as defined for
di05
(Pr
0.40, 3.02
). The FI attribute for
this parameter is set, and so further filtering is applied when this
parameter is viewed with one of the drive keypads.

The following modes are available for the analog input 3. A current loop
loss trip is generated if the input current falls below 3 mA. In modes 4
and 5 the analog input level goes to 0.0% if the input current falls below
3 mA.
In modes 2 and 4 the destination parameter is at a value equivalent to
0.0% when the input current is less than 4 mA. In modes 3 and 5 the
destination parameter is at a value equivalent to 100.0% when the input
current is less than 4 mA.
When analog input 3 is in thermistor mode the display indicates the
resistance of the thermistor as a percentage of 10k
OFF (0) = Terminal inactive
