Parameters 43
78.02 SPRS min speed % Defines the minimum speed percentage to operate the
SPRS.
SPRS trips if the speed is below this parameter value.
The parameter 78.02 SPRS min speed % along with
parameter 78.06 SPRS Min Speed Hysteresis gives the
minimum speed% within which the SPRS system is operated
based on the nominal motor speed.
65.0
20.0...100.0% SPRS minimum speed. 10 = 1%
78.03 Rotor over voltage
limit
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.
710
690...1000V Rotor overvoltage limit. 1 = 1V
78.04 Rotor max voltage Defines the Rotor maximum Voltage for operation of the
drive.
This voltage is the rotor maximum voltage at zero speed
operation.
3000
1000...3000V Rotor maximum voltage. 1 = 1V
78.05 SPRS Max Speed
Hysteresis
Defines the maximum Hysteresis value to SPRS Max Speed
[%] speed set in parameter 78.01 SPRS max speed %.
This value with SPRS MAX SPEED [%] determines the
maximum speed limit in SPRS Mode.
1.00
0.00...1.00% SPRS maximum speed hysteresis. 100 = 1%
78.06 SPRS Min Speed
Hysteresis
Defines the minimum Hysteresis value to SPRS Min Speed
[%] speed set in parameter 78.02 SPRS min speed %.
This value along with SPRS Min Speed [%] determines the
minimum speed limit in SPRS Mode.
1.00
0.00...1.00% SPRS minimum speed hysteresis. 100 = 1%
