● Check the motor type; the following must apply: p10204 = r0108.12
For testing brake 1 [index 0] or 2 [index 1], initially, those values must be entered, which apply
to both test sequences:
● Brake type
p10202[0,1]
= 0
= 1
= 2
● You define the holding torque of brakes using p10209.
● Test torque ramp time p10208[0,1]
Within this time, before starting the test sequence, the test torque is ramped up – and at the
end of the sequence, is ramped down again.
Note
When testing an external brake, whose mechanical design exhibits backlash (e.g. if there is
a gearbox located between the motor and external brake), it can make sense to extend the
ramp time (p10208) when ramping up and ramping down the test torque.
● The interconnection of the parameters for the telegram extension, relevant for SCC/SIC,
can be performed automatically by setting p60122 = 701. However, the telegram extension
must have been previously created. More detailed information on this can be found in
Chapter "Safety Info Channel and Safety Control Channel (SIC/SCC) (Page 212)".
● The following parameters must also be set if you control the brake test using BICO signals
(p10203 = 1):
p10230.0
p10230.1
p10230.2
p10230.3
p10230.4
p10230.5
