- Motor control modes:
- Voltage Frequency Control (VFC)
- Sensorless Flux Control (SFC)
- Field Oriented Regulation (FOR)
- Four complete user data sets can be administered.
Performance of PLC firmware
- The PLC firmware comprises the basic firmware software package and a PLC application platform based on it.
- PLC application plaform: The programming of the PLC sequencer program is line-oriented and is similar to the BASIC programming language.
This cuts down on the time spent learning the control commands. It also has the advantage that the programs are readable by the user without having detailed knowledge of the command set. Handling of the standard parameter is retained. - The PLC sequencer program permits:
- flexible presetting of control and setpoint information for all motor control modes
- setting/reading of analog and digital inputs/outputs
- direct read/write access to all parameters
- mathematical operations (+,-,*,:, modulo, ABS, round
- time or count functions (12 timer, 11 counters)
- and allows handling of integer variables, floating-comma variables and flags
- simple position control
- The command set comprises:
- step commands
- subroutine call
- set commands
- wait commands
- control, positioning and movement commands
