Description
SPRS.
SPRS trips if the speed is below this parameter value.
The parameter 78.02 SPRS min speed %
parameter 78.06 SPRS Min Speed Hysteresis
minimum speed% within which the SPRS system is operated
based on the nominal motor speed.
SPRS minimum speed.
Defines the rotor overvoltage limit to operate the drive in
SPRS Mode.
This value is the maximum Rotor overvoltage limit at which
the drive is operated.
Rotor overvoltage limit.
Defines the Rotor maximum Voltage for operation of the
drive.
This voltage is the rotor maximum voltage at zero speed
operation.
Rotor maximum voltage.
Defines the maximum Hysteresis value to SPRS Max Speed
[%] speed set in parameter
This value with SPRS MAX SPEED [%] determines the
maximum speed limit in SPRS Mode.
SPRS maximum speed hysteresis.
Defines the minimum Hysteresis value to SPRS Min Speed
[%] speed set in parameter
This value along with SPRS Min Speed [%] determines the
minimum speed limit in SPRS Mode.
SPRS minimum speed hysteresis.
