+24 V supply for the brake control, tolerance range +18...30 V
0 V supply for the brake control
Output, brake control axis 1 and axis 2,
max. current is 500 mA
A UL–certified miniature fuse (max. 3.15 A) must be provided at the supply for
the brake control:
Value: e.g. 3.15 AT/250 V; 5x20 mm UL
Company: Wickmann–Werke GmbH
Annenstrasse 113
58453 Witte, Germany
Order No.: 181
Reader’s note
Connection example for a holding brake, refer to Chapter 5.1.1.
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”.
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 Default shift factor: 4
DA2: Speed setpoint Default shift factor: 6
DA3: Actual speed Default shift factor: 6
M: Reference point (ground)
Resolution: 8 bits
Rated operating voltage: 0...5 V
Maximum current: 3 mA
