No pole sensor required. The Initial Magnetization Estimation function detects the position of the magnetic pole when the power is turned on. So, you do not have to reposition themagnetic pole after replacing the encoder.

The Varispeed L7 has enhanced functions to assure a smooth, quiet, and safe ride and it has a high efficiency for energy savings.
■ Zero servo and Starting torque compensation (load sensor is required)realize smooth start-up。
■ S-curve operation realizes smooth acceleration and deceleration。
■ Advance control suppresses torque vibration。
Without advance control With advance control
Torque reference
■ The alarm detection prevents an elevator from moving unexpectedly in case ofincorrect parameter settings, incorrect wiring, or motor failure.
■ The backup battery ensures safe elevator travel in case of power loss.(An optional battery unit(Note)ensures the 48/96 VDC input.) * under develpment

■ One motor MC instead of two while keeping compliance to theEN81-1:1998 • The hardware baseblock function using the
terminals BB and BB1 must be used to enable/disable the Inverter.
• If the elevator safety chain is opened, the Inverteroutput must be cut. This means that the baseblocksignals at the terminals BB and BB1 must be opened, e.g. via an interposing relay.
• The baseblock monitor function must beprogrammed for one of the multi-function outputs (H2-xx = 46/47). The regarding multi-functioncontact must be implemented in the magneticcontactor supervision circuit of the controller inorder to prevent a restart in case of an Inverterbaseblock or motor magnetic contactor malfunction.
• All magnetic contactors must be conform to the EN81-1:1998.
