HEIDENHAIN iTNC 530 HSCI - Module 9143 Activate the Brake Test

928 HEIDENHAIN Technical Manual iTNC 530 HSCI
Module 9143 Activate the brake test
With this module an axis-specific brake test with the configuration from the
machine parameters or with other values for MPs 2230 and 2232 can be
started.
Constraints:
 Synchronized axes
For synchronized axes, only the brake test of the master can be configured
and requested via the PLC module. If a brake test for an associated slave
drive of the synchronized axis is configured via MP2230.x, then the slaves
are automatically tested together with the master. The settings in the
machine parameters are used for the brake test of the slave drives.
In order to start the brake test of synchronized axes via PLC Module 9143,
all drives of a synchronized axis must be switched on via the PLC program
before the brake test can be performed. If a servo drive involved is not
switched on, the brake test is canceled with the error message 8330 Brake
test was canceled.
 Programming in a submit job blocks other submit jobs until the test is
completed.
 The PLC module automatically passes the processing time to other spawn
and submit processes.
Call:
PS K/B/W/D <Axis number>
0 = 1st axis, 1 = 2nd axis, etc.
PS K/B/W/D <Multiplier for motor stall current>
Value in 1/1000 or
0: Default MP2230 (factor of nominal current)
PS K/B/W/D <Permissible traverse path>
Value in 0.1 [um] or
0: Default MP2232
