6.2 Resolver (X7)
6.2.1 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 C00603 2 as a response for
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 C00495 . 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 (
C00926/1 ) 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) . ( 358)
• 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:
Pole position
8400
( C00926/1 ) = - (pole position
9400_C58/1
+ 180 °)
