36.1.4. TORQUE LIMIT SOURCE
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 optional board);
7. Keypad (remotable display/keypad);
8. Encoder (in terminal board MDI6–ECHA , MDI7–ECHB or optional 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.
36.1.5. REMOTE/LOCAL MODE
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
INPUTS MENU.
