The source of the Torque Limit can be selected with parameter
C147
.
The Torque limit function is a limit of the absolute value of the torque required from the drive.
(– Torque limit) <= torque <= (+ Torque limit)
The torque limit references may be selected from the following:
0.
Source disabled
1.
REF
(
single–ended analog input from terminal board
);
2.
AIN1
(
differential analog input from terminal board
);
3. AIN2
(
differential analog input from terminal board; see also the ENCODER/FREQUENCY INPUTS MENU);
4.
FIN
(
frequency input from terminal board
);
5.
Serial link
(
with MODBUS protocol
);
6.
Fieldbus
(
fieldbus on option board
);
7.
Keypad
(
remotable display/keypad
);
8.
Encoder
(
in terminal board MDI6–ECHA , MDI7–ECHB or option board
);
9.
Up Down from MDI (Up/down from digital inputs, see C161 and C162
)
10.
XAIN4
(
auxiliary, differential voltage analog input from ES847 terminal board)
11.
XAIN5
(
auxiliary, differential current analog input from ES847 terminal board)
NOTE
If the reference source is disabled, the torque limit results from the max. absolute torque
determined by the drive size and the motor size.
The max. absolute torque is the max. value ranging between the absolute values of
C047
and
C048
(motor 1, and relevant parameters for motor 2 and motor 3).
Max. absolute torque
= Max( |
C047
| , |
C048
|)
Factory setting is
C147
=0: the reference source is disabled and the torque limit is given by the max. absolute torque.

According to factory-setting, switching over from the
Remote
mode to the
Local
mode can only be made when the
drive is disabled. The reference and command sources for the
Remote
mode depend on the settings of parameters
C140
to
C147
in the CONTROL METHOD MENU
and on the settings of
parameters
C285
to
C287
in the PID
CONFIGURATION MENU. When switching over from the Remote mode to the Local mode, the command and
reference can be sent via keypad only. This is true for the switch over from the
Local
to the
Remote
mode as well.
Parameter
C148
allows customizing the Loc/Rem function so that it can be performed even when the drive is running.
Parameter
C148
also allows setting whether the same running condition and the same reference must be maintained
when switching over from the Remote to the Local mode.
NOTE
For more details on the Loc/Rem function, see LOC/REM Key (Keypad Pages) and
DIGITAL INPUTS MENU
