Reader's note
Connection example for a holding brake, refer to Chapter 4.1.1.
Terminals B1, B2
Input, external zero mark (BERO), axis 1 and axis 2.
Rated operating voltage: +13 to 30 V
If the referencing of the encoder zero pulses cannot be evaluated, then a signal
supplied from a mounted sensor (BERO) can be fed via this input as an "equiv-
alent zero mark".
DAC assignment
Three 8–bit digital/analog converter (DAC) channels are available. An analog
image of various drive signals can be connected through to a test socket via
these converters.
The three DAC channels are assigned the following drive signals by default:
DA1: Current setpoint
DA2: Speed setpoint
DA3: Actual speed
M:
Resolution: 8 bits
Rated operating voltage: 0...5 V
Maximum current: 3 mA
