Parameterising the resolver
Danger!
• If the resolver is used as motor encoder:
Safe operation of the motor is no longer ensured in the event of an error!
• If servo control (SC) or V/f control (VFCplus + encoder) are used:
For safety reasons, always select "Fault" (Lenze setting) in
the (open-circuit) monitoring of the resolver!
Note!
If a Lenze motor with resolver is used, the resolver is the only item that can be selected
as speed sensor in
. Further resolver parameter setting is not required.
Moreover, Lenze synchronous motors do not require a pole position identification (PLI)
as the resolvers of the Lenze synchronous motors are pre-adjusted.
Note!
Acceptance of the resolver pole position from a Servo Drive 9400
The resolver pole position (
) cannot be simply accepted from a Servo Drive
9400 if the pole position (C58/1) considerably differs from -90 ° in the Servo Drive 9400.
• We always recommend a
pole position identification (PLI)
• As an alternative, the following conversion has to be carried out for a transfer of the
resolver pole position from a Servo Drive 9400 to the 8400 TopLine:
