The control functions of outputs 1 and 2 can be freely combined
1
:
- Controller off
- Limit controller
- Pulse width controller
- Pulse frequency controller
1
Exception: When using a modulating controller, outputs 1 and 2 must
have the same configuration.
The controller functions are determined by the following parameters:
