Application Guide
A I/f Start Current
B Output Frequency
7.107 (ID 535) I/f Start Frequency
Location in the menu:
•
INU application: P3.1.4.12.2
Use this parameter to set the output frequency limit below which the set I/f start current is fed to motor.
When the output frequency of the drive is below the limit of this parameter, I/f start function activates. When the output frequency
is more than the limit, the drive operation mode changes back to the normal U/f control mode.
7.108 (ID 536) I/f Start Current
Location in the menu:
• INU application: P3.1.4.12.3
Use this parameter to set the current that is used when the I/f start function is enabled.
7.109 (ID 600) Control Mode
Location in the menu:
• INU application: P3.1.2.1
• AFE application: P3.2.1
Use this parameter to set the AC drive control mode.

7.110 (ID 601) Switching Frequency
Location in the menu:
• INU application: P3.1.2.6.1
• AFE application: P3.2.7.1
Use this parameter to set the switching frequency of the AC drive.
If you increase the switching frequency, the capacity of the AC drive reduces. To reduce capacitive currents in the motor cable,
when the cable is long, we recommend that you use a low switching frequency. To reduce the motor noise, use a high switching
frequency.
7.111 (ID 602) Field Weakening Point Frequency
Location in the menu:
• INU application: P3.1.4.2
Use this parameter to set the output frequency at which the output voltage reaches the field weakening point voltage.
7.112 (ID 603) Voltage at Field Weakening Point
Location in the menu:
• INU application: P3.1.4.3
Use this parameter to set the voltage at the field weakening point as a percentage of the motor nominal voltage.

Description
The frequency reference of the drive is set to the output frequency without slip compensa-
tion. The motor load specifies the actual speed of the motor.
The frequency reference of the drive is set to the motor speed reference. The motor load does
not affect the motor speed. There is slip compensation.
The motor torque is controlled. The motor produces torque in the set speed limits to achieve
torque reference.
