Motoring drive commissioning

7.4.1

Motoring drive enable

When the Regen drive has been successfully synchronised, Pr 3.09 on
the Regen drive will become active and digital output F1 on terminal 24
also becomes active allowing the motoring drive(s) to be enabled. If the
Regen drive trips or attempts to re-synchronise to the supply, Pr 3.09
becomes zero and the enable signal for the motoring drive(s) is
removed.
The setting of certain parameters in the motoring drive must be given
special consideration when used in a regen system.
7.4.2

Ramp Mode - Pr 2.04 (Pr 0.15)

When a motoring drive is used in a regen system, the ramp mode should
be set to FAST. The default setting of standard control will result in
incorrect operation.
7.4.3 Voltage Control Mode - Open loop only Pr 5.14
(Pr 0.07)
The default setting of UR_I does not function correctly in the motoring
drive when used in a regen system. When the system is powered up, the
motoring drive is disabled while the Regen drive synchronises to the AC
supply. The resultant delay before the motoring drive is enabled means
that the stator resistance test cannot be completed. When open loop
vector operation is required the voltage mode should be set to UR_S.
7.4.4

AC Supply Loss Mode - Pr 6.03

The motoring drive will not operate correctly if the AC supply loss mode
is set to STOP. If the AC supply is lost, the Regen drive disables the
motoring drive and prevents a controlled stop from being completed.
