Warning Diagnostic Messages (Exxxx)
E2074 Encoder 1: encoder signals disturbed
Cause
Defective encoder cable or cable shielding
Measuring system defective
Faulty mounting of measuring head in the case of
linear measuring systems
Measuring system dirty
Hardware defect on control section of drive
LSA Control S.L. www.lsa-control.com [email protected] (+34) 960 62 43 01
Supported by Firmware Variant:
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;
communication phase 2.
Remedy
Check cable to measuring system and replace it, if
necessary
Check measuring system and replace it, if necessary
Check mounting of measuring head and correct it, if
necessary
Clean or replace measuring system
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.
