ENCODER FEEDBACK CONTROL—A500(L)
4.8.3 Pr. 22 "torque restriction level" (factory setting: 150%)
Torque restriction may be activated only when vector control is selected. The second and third functions
are Pr. 48 "second torque restriction level" and Pr. 144 "third torque restriction level".
When vector control is not selected, the stall prevention functions are activated. Use the same parameter
numbers for setting. (Refer to the Inverter Instruction Manual.)
The Pr. 22 setting may be changed during operation.
When Pr. 22 = "9999", the torque restriction level may be set by entering a signal into the No. 1 terminal. At
this time, the auxiliary input override function of the No. 1 terminal is not activated.
The variable torque restriction level analog signal can be restricted.
4.8.4
Pr. 371 "torque characteristic selection" (factory setting: 1)
Used to change the torque characteristic according to the machine characteristics.
Pr. 371 Setting
Standard Motor with encoder (e.g. SF-JR)
0
Cyclic operation mode (CAUTION)
1 (factory setting)
Continuous operation mode
CAUTION
When the cyclic operation mode is used, the inverter capacity must be made one rank higher than
the motor capacity.
