Frequently Asked Questions
Which motor types are supported
Standard three phase induction motors are supported. Sensorless vector control improves low speed torque and regulation. Check the manual if using special motors.
Does this model include Safe Torque Off
Yes. STO is built into the B1 series and can be wired to meet the required safety performance level when installed correctly.
What overload can it handle
Heavy duty overload is 150 percent for 60 seconds, 180 percent for 10 seconds and 200 percent for 1 second to cover starting and transient loads.
What communications are available
Built in RS-485 with Modbus RTU. Optional cards are available for Ethernet or other fieldbus protocols depending on system requirements.
What are the physical dimensions
Approx. 80 x 185 x 140.5 mm frame size. Allow additional space for cables and airflow inside the panel.
