C047 (C090, C133) Minimum Torque
C047 (Motor 1)
C090 (Motor 2)
C133 (Motor 3)
Range
–5000 ÷ 5000 (*) –500.0% ÷ +500.0%
Default
0
0.0%
Level
ADVANCED
Address
1047, 1090, 1133
Control
VTC and FOC
Function
This parameter sets the min. limit of the torque demanded by the control being
used.
Torque is expressed as a percentage of the rated torque of the selected motor.
NOTE
If an external torque limit is set (C147 in the CONTROL METHOD MENU), the values set
in the parameters above represent the range of the source used for limitation; they can
be reduced by adjusting the external source; the torque ramp times set in the
RAMPS
MENU will be applied to the preset limit torque reference (P026–P027).
C048 (C091, C134) Maximum Torque
C048 (Motor 1)
C091 (Motor 2)
C134 (Motor 3)
Range
–5000(*) ÷ 5000 (*) –500.0% ÷ +500.0%
Default
1200
120.0%
Level
BASIC (C048); ADVANCED (C091;C134)
Address
1048, 1091, 1134
Control
VTC and FOC
Function
This parameter sets the max. limit of the torque demanded by the control being
used.
Torque is expressed as a percentage of the rated torque of the selected motor.
NOTE
If an external torque limit is set (C147 in the CONTROL METHOD MENU
), the values set in the
parameters above represent the range of the source used for limitation; the torque ramp times
set in the RAMPS MENU will be applied to the preset limit torque reference (P026–P027).
C050 (C093, C136) Frequency Decrease during Acceleration Limit
C050 (Motor 1)
C093 (Motor 2)
C136 (Motor 3)
Range
0 ÷ 1
0: Enabled
1: Disabled
Default
0
0: Enabled
Level
ADVANCED
Address
1050, 1093, 1136
Control
IFD
Function
This parameter enables output frequency decrease during acceleration limit.
NOTE
Setting “1:Disabled” is recommended for high inertia loads. When high inertia loads are
connected to the drive, the frequency decrease can lead to strong regeneration and DC-bus
voltage oscillations.
