6. Function Description
6-10
1.10) Main Drive
Each inverter linked to system can be controlled separately. When this terminal is turned On, changing
operating speed reference, operating method, and torque limit is done via only Keypad without changing
the user-setting parameter value.
When ‘Main Drive’ terminal is turned On, Main Drive operation is available as shown below condition
.
z Inverter during stop: It is applied immediately.
z Inverter during operation: It is applied after stop.
The parameter value of FUN_01 Run/Stop Src, FUN_02 Spd Ref Sel, CON_28 Trq Lmt Src related with Operating
speed reference, Operating method, and Torque limit is not applied when ‘Main Drive’ terminal is turned On even
though parameter is changed via keypad or communication. It is applied when the terminal is turned Off during
stop.
The parameter value of CON_01 Control Mode is operated same as above parameter described.
The setting of Operating speed reference, Operating method and Torque limit is set as shown below.

1.11) 2nd Func (the 2
nd
function setting)
The iV5 inverter has the capability to control 2 motors independently. A second motor may be active by selecting one
terminal for this function and turn it ON. 2
nd
function is not displayed if the terminal is not defined for this or the defined
terminal is OFF.
