The digital and analog programmable outputs and Inputs
Selection of the MCM reference
The selection of one of the 4 MCM sensitivity level is made by applying
25V to the 2 terminals X2/6 and / or X2/7 using a BCD coding.

The Sample Hold of the MCM function
"Sample" command for motor current monitor in Sample & Hold mode
(measure and store motor current under no-load conditions). Used
mainly for gap elimination.

when function is
selected from the terminal block. Tolerance of the current limit is -10% /
+15%. This resistor is often integrated into the spindle connector to
provide automatic current limitation setting for different spindles.

SDIG+
SDIG-
Digital output from converter clock. The number of motor poles (as set in
Menu B – max. 24 poles) is taken into consideration so that the signal
SDIG is a true indication of the set speed respectively the motor speed in
RPM if the speed measurement option is integrated. Output frequency time
10 equal speed in RPM. Signal level 24 VDC, 20 mA

CDI+
CDI-
Input for rotor incremental encoder. Signal level 24 VDC, 20 mA.
If the signal is supplied by a magneto-resistive sensor, use the TACHO
PRINT option to shape the signal.
