Modes
Encoder Mode
At encoder mode feedback information is coming from the encoder signals. The encoder is
mounted at the motor. The speed regulation has got a high performance at each load
condition and qualified for each application to control exactly the speed of a system
especially for low speed application. The maximum achievable speed in this mode is limited
through the encoder input frequency.
Remark:
The modes below are possible with the drive but not advisable. Use in this case the
SCA-LS-30-03. The descriptions and wiring examples for these modes are all
described in the manual of the SCA-LS-30-03.
Voltage Mode
In the voltage mode the drive is watching the output voltage as a feedback voltage. The
drive can not regulate the speed exactly if the motor is loaded with a higher load. This mode
is used e.g. in conveyors with nearly constant load to control the speed.
