If an RS 422 interface (OPT.2) is installed in the controller, motor rotation
monitoring can be implemented (fig. 1-8). For this purpose, the parameter
P20 = 2 must be set on the front panel and a type 1000 encoder must
be installed on the stepping motor. Rotation monitoring
The rotation monitoring feature compares the set and actual positions of
the motor and reports a rotation monitoring error if the difference between
set and actual position exceeds a certain limit value (18 steps).
NOTE
Rotation monitoring is possible in all modes except electronic gear mode
(P00 = 3).
The input AUTOM can be used (depending on the interface configura-
tion) for selecting one of the following modes: Manual and automatic mode
Input AUTOM = 0
– Parameter and data input via front panel or
– Manual mode or
– Teach-in mode or
– Upload/download (only with serial interface, if parameter P00 = 0)
Input AUTOM = 1
– Oscillator mode via inputs/outputs or
– Oscillator mode via analog interface or
– Position processing mode via inputs/outputs or
– Electronic gear (only with encoder interface, if parameter P00 = 3)
NOTE
In on-line command processing mode, mode selection via the AUTOM
input is only possible if parameter P69 = 1.
