SIMOVERT MASTERDRIVES
A fiber-optic cable is used as the transfer medium in SIMOLINK.
Plastic or glass-fiber optic cables can be used.
For cable lengths (the distance between two nodes) up to a maximum
of 40 m, plastic cables are used.
Recommendation:
Plastic fiber-optic cables from Siemens; CA-1V2YP980/1000,200A
For cable lengths (distance between two nodes) up to max. 300 m,
fiber-optic cables with a glass core and a plastic sheath can be used.
Recommendation:
Fiber-optic cables with glass core from Siemens; CLY-
1V01S200/230,10A
The above-mentioned fiber-optic cables do not have an outer sheath.
When using them for wiring outside switch cabinets, the cables must
either be laid in cable ducts or conduits or suitable cables with an outer
sheath must be used. On cables with an additional outer sheath, this
must be removed before fixing the connector at the end of the cable as
the connectors cannot accommodate the sheath. Therefore, when
selecting the cable, one must make sure that the then remaining outer
fiber diameter of 2.2 mm for attaching the connector is maintained.
The SLB optional board has a 24 V voltage input for the external
voltage supply of the board. This ensures that data transfer is
maintained in SIMOLINK even with powered-down converter/inverter.
Changeover between internal voltage supply from the converter/inverter
and external voltage supply is carried out automatically, with priority
being given to the external voltage supply.
A changeover must not be performed during bus operation because it
generates a reset signal on the option board as a result of which bus
operation is interfered with.
If the SLB option board is continuously supplied with external voltage,
switching the internal voltage supply on and off (on/off switching of the
CU) after the internal voltage supply is switched on will result in a bus
operation fault. Fault-free operation after switching in the internal
voltage supply is only possible under the following conditions:
♦ SLB in transceiver operation and with part number 477 458 9000 15
♦ CU has firmware version MASTERDRIVES MC from V1.66 or
MASTERDRIVES MC Performance 2 from V2.32,
MASTERDRIVES VC from V3.42
♦ Before switching off, the SLB option board was actively participating
in bus operation (i.e. the SLB was correctly parameterized by the
CU)
