Basic parameters 2

6.8.1 Switching motor characteristics via terminal input
f170 : Base frequency 2
f171 : Base frequency voltage 2
f172 : Torque boost value 2
f173 : Motor electronic-thermal protection level 2
f185 : Stall prevention level 2
 Function
Use the above parameters to switch the operation of two motors with a single inverter and to select
motor V/F characteristics (two types) according to the particular needs or operation mode.
Note: The pt (V/F control mode selection) parameter is enabled only for motor 1.
If motor 2 is selected, V/F control will be given constant torque characteristics.

*1: These are parameters set by setup menu. Default setting value is "jp". Refer to section 11.5.
*2: The inverter's rated current is 100%. When f701 (current and voltage unit selection)
= 1 (A (amps)/V (volts)) is set, it can be set at A (amps).
*3: After the motor change, please drive after 0.2 seconds or more.
