08.96 Description
SIMOVERT SC
The inverter open-loop control uses a microprocessor with field-oriented vector control, with a very fast
secondary closed-loop current control. High drive dynamic performance is achieved as a result of the field
oriented vector control. When the unit is shipped, the pulse frequency is preset to 5 kHz. It can be set in the
range from 5 kHz to 7.5 kHz.
SIMOVERT SC is suitable for:
♦ Single-motor drives with permanent-field 1FT6 motors
Some of the applications are, for example
♦ Winder drives,
♦ Foil machines,
♦ Packaging machines
After power-up, only the motor must be selected and the drive can then be enabled. The drive can be matched to
the load moment of inertia and optimized by changing a closed-loop control parameter.
The converter operates with motor identification (MOTID). The maximum stator frequency is 400 Hz.
The following operating modes can be selected:
♦ Closed-loop speed control
♦ Closed-loop torque control
The following encoders can be used:
♦ ERN 1387 encoders
♦ Encoders which are compatible to ERN 1387
♦ Resolvers
