Refresh enc 2
Enable the monitoring of the encoder 2 (connector XE2) connection status, in order to
detect a speed feedback loss alarm.
When an alarm is detect, the keypad will shown „Speed fbk loss“.
Encoder 2 state
provides the indication of encoder 2 connection status. The parameter can be programmed
on a digital output. This function is activate setting
Enable fbk contr
= Enabled.
Encoder 1 state
Provides the indication of the encoder 1 (connector XE1) connection status. The pa
-
rameter can be programmed on a digital output.

The
Tacho scale
and
Speed offset
parameters are used for a fine scaling of the speed feedback
circuit. When the factory set parameters are loaded (
Load default
) these two parameters do
not undergo any change, so that a new scaling is not necessary!
Following parameters allows to determine the machine absolute zero and perform a positioning control by us
-
ing the APC300 option card:
Enable ind store
This parameter enables the reading of the encoder index and qualifying signal that could
be used in a system for implementation of position control.
Enabled
This setting enables the reading of the encoder index.
Disabled
This setting disables the reading of the encoder index
Ind store ctrl
Control register for the encoder index and qualifying signal (*).
Index storing
Status register and function data.
(*) Index qualifier signal is not supported by regulation card R-TPD3G revision f (product configuration “D1”)
and lower
Ind store ctrl parameter [92]
