Take VFD007EL21W(-1) as an example, assume that the ambient temperature is 40°C, the drive output
current must be controlled within 100% of the rated current. If the ambient temperature is 50°C, the drive
output current should not exceed 80% of the rated current. For other models in an ambient temperature of
50°C, the drive output current must be controlled within 100% of the rated current; for other models in an
ambient temperature of 60°C, the drive output current must be controlled within 80% of the rated current.

Take VFD007EL21W(-1) as an example, assume that the ambient temperature is 40°C, and default carrier
frequency is 8 kHz, then the drive output current reaches 100% of the rated current; if the carrier frequency is
12 kHz, the drive output current must be controlled within 80% of the rated current. If the ambient temperature
is 25°C, the installation method is single drive installation, and the carrier frequency is 12 kHz, then the drive
reaches 100% of the rated current.

02.05 Power-On Command and Run Command Source Modifies the Drive Operating Control
Default: 1
Settings 0: Start running when power is on.
1: Do not run when power is on.
2: When the source of the command changes, the drive’s operation remains the
same.
3: When the source of the command changes, the drive’s operation follows the new
command.
4: The motor drive can start to run at power on or after reset.
