Fn_82
:
Energy Savings
xx00:
Energy Savings disable
xx01:
Energy Savings controlled by Multi-Function Input Terminals using Preset Speed
functions.
Fn_83
:
Energy Savings Gain:
0 - 100%
1. This function can be applied to Fans or Pumps that have loads with high starting inertias. In
these types of applications, where the load is heavy during start-up but tapers off to a variable
torque type load at some point in the ramp curve, using function (Fn_83) to adjust the suitable
gain (voltage level) at the target speed will reduce the V/Hz ratio saving energy.
2. The Energy Savings function is available only if (
Fn_56
) (
Fn_57
) or (
Fn_58
) Multi-Function
Inputs are set to (08) or (24).
3. When the Multi-Function Input Terminal is turned ON, and (
Fn_82
) is set to (xx01) and (
Fn_56
)
(
Fn_57
) or (
Fn_58
) are set to (08), the output voltage will decrease gradually to the previous
output voltage x (
Fn_83
). When the input terminal is turned OFF, the output voltage will
gradually increase to the previous voltage.
