How to use the input signals
(assigned terminals DI1 to DI4, STR)
1.11.14 Control mode changing (MC signal):
By setting Pr. 800 "control system selection", change the control mode between speed, torque and position. Refer
to page 182 for details.
1.11.15 Torque restriction selection (TL signal):
By setting Pr. 815 "torque restriction level 2", you can change the torque restriction value. Refer to the Instruction
Manual (basic) for details.
1.11.16 Start time tuning (X28 signal):
You can perform online tuning before turning on (during stop) the start signals (STF, STR) to prevent a start time
delay due to tuning.
POINT
• Perform offline auto tuning (page 132) and set "1" in Pr. 95 (start time tuning).
• You can perform start time tuning by X28 signal when the Y39 signal is off.
• It takes 500ms maximum for start time tuning to complete.

Start signal
REMARKS
• Start time tuning is also performed with the LX signal on and a start signal by the speed command less than the starting
speed (e.g. zero speed command) on.
• The Y39 signal is kept on while the second magnetic flux remains after a motor stop.
• The X28 signal is not made valid while the Y39 signal is on.
• The STF, STR and LX signals are made valid after completion of start time tuning.
• During tuning, only the output signals below are valid IPF, THP, PU, Y12, RY, ER, LF, MT, DA1, DA2, ABC.
• Invalid during V/F control.
1.11.17 Torque bias selection 1 (X42 signal):
Torque bias selection 2 (X43 signal):
When using the torque bias function, you can combine the on/off of the X42 and X43 signals to select the torque
bias amount. Refer to page 189 for details.
