•
Maximum short-term tensile force: 50 N
•
Minimum short-term bend radius: 25 mm
•
Minimum long-term bend radius: 35 mm
•
Maximum long-term tensile load: 1 N
•
Flexing: Max. 1000 cycles
ABB drive products in general utilize 5 and 10 MBd (megabaud) optical components from
Avago Technologies’ Versatile Link range. Note that the optical component type is not
directly related to the actual communication speed.
Note: The optical components (transmitter and receiver) on a fiber optic link must be of the
same type.
Plastic optical fiber (POF) cables can be used with both 5 MBd and 10 MBd optical
components. 10 MBd components also enable the use of Hard Clad Silica (HCS
® ) cables,
which allow longer connection distances thanks to their lower attenuation. HCS
®
cables
cannot be used with 5 MBd optical components.
The maximum lengths of fiber optic links for POF and HCS ® cables are 20 and 200 meters
respectively.

ES voltage control
accuracy (static)
Voltage error < 1% of the drive nominal voltage (converter with the optional
BAMU voltage/current measurement unit)
Note: If the converter does not include the BAMU voltage/current measurement
unit, the voltage measurement accuracy depends on the customer’s
measurement device.
