Actual signals and parameters
207
77 LOAD SPEED CTRL
Settings for Load speed control. See section
on page
Note:
The Base speed versus Motor current graph is plotted using the
parameters
. These parameters have to be configured in the
correct sequence and if the sequence of values in these parameters are not
correct, the speed will be limited to Par.
Base speed. For more
information, see section
on page
123.
77.01
LOAD SPD CTRL
SEL
Defines the Load speed control function activation command. If this selection
command is not active then the speed limit is not calculated with this function.
NOT SEL
No Load speed control.
1
ENABLE
Load speed control always active.
2
COMM.MODULE
Load speed control through APPL CONTROL WORD (3.34) bit 2.
3
PARAM 77.02
Load speed selected with Par.
LOAD SPD CTRL PTR.
4
77.02
LOAD SPD CTRL
PTR
Defines the source or constant for value Par. 77.02 LOAD SPD CTRL PTR of
parameter
LOAD SPD CTRL SEL.
-255.255.31 …
+255.255.31 / C.-
32768 … C.32767
Parameter index or a constant value:
- Parameter pointer: Inversion, group, index and bit fields. The bit number is
effective only for blocks handling boolean inputs.
- Constant value: Inversion and constant fields. Inversion field must have value
C to enable the constant setting.

77.03
HOLD RAMP
Defines time period for holding the speed reference after which the motor has
crossed the base speed to check for the motor current. This motor current after
this time period delay is regarded by the function as the base speed current for
the particular load used.
0.00 … 5.00 s
The speed reference holding time.
0 … 500
77.04
CURRENT X1 FWD
Defines the current in amps expected at the base speed in forward direction for
limiting the speed reference to the value in parameter
REF Y1 FWD.
This current can be the empty hook current at the base speed when running in
the forward direction.
0.0 … 3000.0 A
Setting range in amps.
0 … 30000
77.05
REF Y1 FWD
Defines the speed in rpm to be used as the speed limit in forward direction, if
the current at the base speed in forward direction is equal to the value in
parameter
CURR X1 FWD. This value can be the maximum allowed
speed in empty hook condition in the forward direction.
0.0 … 18000.0 rpm
Setting range in rpm.
0 … 180000
77.06
CURRENT X2 FWD
Defines the current in amps expected at the base speed in forward direction for
limiting the speed reference to the value in parameter
REF Y2 FWD.
0.0 … 3000.0 A
Setting range in amps.
0 … 30000
77.07
REF Y2 FWD
Defines the speed in rpm to be used as the speed limit in forward direction, if
the current at the base speed in forward direction is equal to the value in
parameter
CURR X2 FWD.
0.0 … 18000.0 rpm
Setting range in rpm.
0 … 180000
77.08
CURRENT X3 FWD
Defines the current in amps expected at the base speed in forward direction for
limiting the speed reference to the value in Parameter
REF Y3 FWD.
0.0 … 3000.0 A
Setting range in amps.
0 … 30000
77.09
REF Y3 FWD
Defines the speed in rpm to be used as the speed limit in forward direction, if
the current at the base speed in forward direction is equal to the value in
parameter
CURR X3 FWD.
0.0 … 18000.0 rpm
Setting range in rpm.
0 … 180000
