F4002 Double MDT failure shutdown
Cause
Bus master does not send any more cyclic telegrams
to the drive. These, however, are expected in
communication phase 4
Fiber optic cable bus: disturbance in fiber optic
transmission line
Fiber optic cable bus: Input power of light signals too
low
Light power to be measured at receiver (with test
mode: continuous light) must be between
–20 dBm (10 µW) and –5 dBm (320 µW)
Disturbance in SERCOS interface (general)
Different transmission times of master data
telegrams in master and slave
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:
The master data telegram (MDT) was not received in the drive in two
successive SERCOS or field bus cycles. The drive goes back to
communication phase 0.
Remedy
Switch master on and start cyclic communication; see
manual for control unit
Check all fiber optic cable connections in SERCOS ring
Adjust transmitting power or check attenuation of fiber
optic cable.
Maximum attenuation between TX and RX mustn't
exceed 12.5 dB
Replace control section or entire drive controller
Synchronize transmission times of master data
telegrams in master and slave
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.
