Cross-monitoring
You can use cross-monitoring to set reciprocal monitoring of 2 devices for
compliance with the set voltage limit values. At least 2 devices with different
CAN bus addresses are needed for cross-monitoring.

Figure 58: Cross-monitoring
For the check, the measured voltage of the device
is transmitted to the
device
via a second separate measurement input and vice versa. The
calculated measured voltage is compared with the original measured values
via the CAN bus. If the measured values deviate, the
Measured value error
message is issued.
When checking the limit values, one device transmits a measured voltage to
the other via the second separate measurement input. You can set the fol-
lowing limit values for this measured value:

As soon as one of the set limit values is exceeded, once the set delay time
for the error message [
96] has lapsed, the
Measured value error
mes-
sage is output. If wired accordingly, relay contacts can block the raise/lower
pulse to the motor-drive unit. Regulation of individual devices is not affected
by limit value monitoring.
The following sections describe how you set the relevant parameters for the
monitoring device.
