ƒ By giving a stop command during torque control, operation changes to speed control automati-
cally, and the motor decelerates to stop. The torque limit during deceleration to stop becomes the
values set in the torque limit parameters (L7-01 to L7-04).
Note:
The control mode actually changes after the speed/torque control selection command changes
and after the reference delay timer (D5-06) elapses. The terminal 13 speed reference/speed
limit and the terminal 16 torque limit/torque reference are stored in the inverter until the time
set to D5-06 elapses.

V/f Pattern
Setting Range:
155 to 255V (230V class), 310 to 510V (460V class) 445 to 733 (575V class)
<1110>
Factory Default:
230V, 460V, 575V
<1110>
Sets the inverter input voltage in units of 1V.
Select between fan-cooled, blower-cooled and vector/inverter duty motor types with this parameter.
Choose a preset V/f pattern for operation in V/f modes only. It may be necessary to change the V/f pat-
tern when using a high-speed motor, or when special torque adjustment is required in the application.
Set values 0 to E:
preset V/f pattern can be selected
F:
custom V/f pattern can be set (factory default)
Preset V/f patterns are automatically scaled by the input voltage value set in parameter E1-01. Set the
V/f pattern according to the applications described in the table on the following page:

1
Blower-cooled or TENV motor characteristics
This setting allows 120% motor current at and above 5.6 Hz
continuously, and allows 100% motor current at 0 Hz continu-
ously (w/ linear in between).

Vector/inverter duty motor
<1110>
This setting allows 120% motor current at all frequencies.
