11.4 Type 3 Position Regulator

The drive’s type 3 position regulator feature bypasses the speed loop, which
eliminates the need to provide a motor speed feedback device. However, the trade-off
is that it may be difficult or, in some system configurations, impossible to achieve
stable operation.

The decision to use this feature was previously established during the configuration of
the current minor loop reference in section 4.1 ((

ATTENTION: The J15 jumper must be set to the torque/current position
when using the WebPak 3000 drive’s type 3 position loop feature.
Applying a drive as a direct current regulator has safety issues that must
be considered. Failure to observe this precaution could result in severe
bodily injury or loss of life.
