Product overview
All parameters required for sensorless operation can be found in the table "Overview of parameter settings
for individual operating modes [
Summary
In this mode, above a minimum speed the motor current without encoder is controlled load-dependent. In
this way it is possible to realise a particularly cost-effective drive in combination with high efficiency. The
achievable dynamic performance of the drive control is slightly reduced compared to the other operating
modes.
Advantages compared with standard mode
• Low current consumption (almost full load-dependence)
• High efficiency
• no encoder required
Prerequisites
• relatively high parameterisation effort required (speed controller + additional parameters)
• minimum speed required (if the speed is too low, the motor automatically switches to standard mode)
• dynamic performance somewhat lower than in standard mode
• Only possible with stepper motors from Beckhoff Automation (AS10xx)
