E2069 Brake torque too low
Cause

- or -
Brake is wetted with oil or grease
Brake is worn (see service life of brake in Project
Planning Manual for motor)
Wiring or control error of brake
(hardware defect on control section)
DOK-INDRV*-GEN-**VRS**-WA01-EN-P
LSA Control S.L. www.lsa-control.com [email protected] (+34) 960 62 43 01
Supported by Firmware Variant:
When the drive enable was switched off the motor moved during the
automatic brake torque check (can be activated via P-0-0525, Holding
brake control word). The motor holding brake therefore no longer
provides the required holding torque (see also P-0-0547, Test torque
with holding brake applied).
Note:
The result of the brake check is displayed in P-0-0539,
Holding brake status word.
Remedy
If warning occurs when drive enable is switched off, start
"brake check" command in order to abrade brake, if this
setting was made in P-0-0525, Holding brake control
word. Afterwards brake should be able to provide full
torque again
If holding torque still isn't reached after repeated start of
"brake check" command (abrasion cleaning processes
of brake), motor holding brake or entire motor needs to
be replaced
Check wiring and connection of brake (incl. brake relay).
If brake control in controller (e.g. relay) is defective,
entire drive controller or control section has to be
replaced
