Motor Control
Open-Loop/Closed-Loop Operation
The IndraDrive firmware supports the following two basic principles of
motor control:
• motor control (U/f control) in open-loop operation
→ open-loop-controlled operation without encoder information
• motor control in closed-loop operation
• with encoder feedback
→ closed-loop-controlled operation (position, velocity and current)
• without encoder feedback
→ closed-loop-controlled operation with motor model (velocity and
current)
Via bit 14 and bit 15 of parameter P-0-0045, Control word of current
controller the method of motor control is selected.
Cycle Times and PWM Frequencies
Depending on the firmware variant (MPH, MPD or MPB) and the
respective control section (CSH01.1, CDB01.1, CSB01.1), there are the
following possible cycle times and PWM frequencies:
