[Reduce Ilmt Sel]

Enables the use of a reduced current limit when in overload.

“Disabled” = The Converter current limit is always the value in parameter 100 -
[Active I Lmt].

“Enabled” = The Converter current limit will switch to the value set by parameter
101 - [Active OL I Lmt] when in overload.

152

[Inductance]

Sets the input filter inductance. When set to non-zero, this value is used to
calculate the tuning coefficients for the current loop CML Ki and Kp.

[CML Bandwidth]

Sets the Current Minor Loop bandwidth. When set to non-zero, this value is
used to calculate the tuning coefficients for the current loop CML Ki and Kp.

Default:

Min/Max:
Units:

1500 Rad/sec

0/4000 Rad/sec
1 Rad/sec

154

[CML Damping]

[Voltage Loop Sel]

Selects the operation of the voltage loop.

“Optimize Ref” = Vdc reference is calculated to minimize switching losses,
based on the measured AC Line voltage and the minimum voltage required by
the Inverter.

“Manual Ref” = The value set by parameter 060 - [DcLink Reference] is used for
Vdc reference.

“Regen Only” = Reserved for future.

“Open Loop” = The Converter outputs a sinusoidal voltage synchronized to the
AC line with an amplitude set by parameter 063 - [Modulation Index]. This
feature requires a password to operate.
