8-36 Warning Diagnostic Messages (Exxxx) Rexroth IndraDrive
DOK-INDRV*-GEN-**VRS**-WA01-EN-P
E2074 Encoder 1: encoder signals disturbed
Supported by Firmware Variant: FWA-INDRV*-MPH02VRS-MS
FWA-INDRV*-MPB02VRS-MS
FWA-INDRV*-MPD02VRS-MS
The hardware checks the signals of the measuring system (encoder 1) for
inadmissible signal dips. If a signal (e.g. sin or cos) leaves the thresholds
monitored by the hardware, the warning E2074 is generated.
In the case of major failures or several signal dips in series, the error
F8022 Enc. 1: enc. signals incorr. is generated and the drive is shut
down. The warning E2074 therefore points at disturbed encoder signals
before a breakdown occurs.
Note: The warning E2074 is only cleared by reinitialization of the
encoder position; i. e. it is necessary to switch to
communication phase 2.
Cause Remedy
Defective encoder cable or cable shielding Check cable to measuring system and replace it, if
necessary
Measuring system defective Check measuring system and replace it, if necessary
Faulty mounting of measuring head in the case of
linear measuring systems
Check mounting of measuring head and correct it, if
necessary
Measuring system dirty Clean or replace measuring system
Hardware defect on control section of drive Replace control section or entire drive controller
Note: Only Rexroth service engineers or especially trained users are
allowed to replace the control section. The replacement of the
entire drive controller is described in the Project Planning
Manual for the power section.
