T
CAUTION
RISK OF DAMAGE TO THE MOTOR
Check that the motor will withstand this current without overheating.
Failure to follow these instructions can result in equipment damage.
2nd level of standstill DC injection current.
This parameter can be accessed if [Auto DC injection] (AdC) is not [No] (nO).
See page 162

0 to 30 s 0 s
g
T
CAUTION
RISK OF DAMAGE TO THE MOTOR
• Long periods of DC injection braking can cause overheating and damage the motor.
• Protect the motor by avoiding long periods of DC injection braking.
Failure to follow these instructions can result in equipment damage.
2nd standstill injection time.
This parameter can be accessed if [Auto DC injection] (AdC) is set to [Yes] (YES).
See page 162

SFr [Switching freq.]
2 to 16 kHz 4.0 kHz
T
CAUTION
RISK OF DAMAGE TO THE DRIVE
On ATV32
ppppM2 ratings, if the RFI filters are disconnected (operation on an IT system), the drive’s switching
frequency must not exceed 4 kHz.
Failure to follow these instructions can result in equipment damage.
Switching frequency setting. See page 106.
Adjustment range: The maximum value is limited to 4 kHz if [Motor surge limit] (SUL) parameter, page 107
is configured.
Note: In the event of excessive temperature rise, the drive will automatically reduce the switching frequency and reset it once
the temperature returns to normal.
CLI [Current Limitation]
0 to 1.5 In (1) 1.5 In (1)
g
T
CAUTION
RISK OF DAMAGE TO THE MOTOR AND THE DRIVE
• Check that the motor will withstand this current, particularly in the case of permanent magnet synchronous
motors, which are susceptible to demagnetization.
• Check that the profile mission complies with the derating curve given in the installation manual.
Failure to follow these instructions can result in equipment damage.
Used to limit the motor current. See page 204.
Note: If the setting is less than 0.25 In, the drive may lock in [Output Phase Loss] (OPL) fault mode if this has been enabled
(see page 238
). If it is less than the no-load motor current, the motor cannot run.
