Operation with increased rated power
Under the operating conditions described here and under continuous operation, the
controller can be operated with a higher power motor (increased rated power). The
remaining overload capacity of the drive system (for 60 s/3 s) is reduced accordingly to
approx. 120 %/160 %.
Typical applications stand out due to low dynamic requirements, e.g. pumps and fans,
general horizontal materials handling technology and line drives.
Required parameterisation
Operation at increased rated power requires the following settings to be made particularly
for the V/f characteristic control (VFCplus), but also for all other types of control:
The controllers that can be operated at increased rated power are listed in the
rated data in the
8400 hardware manual
.
• The hardware manual has been stored in electronic form on the data carrier
supplied with the 8400 drive controller.
Stop!
Operation at increased rated power is only permitted ...
• with the controllers listed in the
8400 hardware manual
for this type of
operation in the stated mains voltage range.
• at switching frequencies of 2 kHz and 4 kHz.
• at a max. ambient temperature of 40 °C.
• with the types of installation stated in the
8400 hardware manual
.
• with the fuses, cable cross-sections, mains chokes, and filters as required in
the
8400 hardware manual
for this operation.
• after parameterisation according to the specifications below.
