300741 Upper limit violated MD POWER ON
POWER ON
Drive only ramps up to ramp-up state 2
During ramp-up control detects that machine data has violated input limits. This occurs with parameters with mo-
tor-dependent limits if the motor maximum speed is reduced and maintained after booting. Another cause might be
the switching off of the input limits (P–90, bit 0). Alter parameter and switch on input limits again.
Additional information:
Number of incorrect machine data
S Correct parameter
S Check all parameters with motor-dependent limits
S Save BOOT drive
S Repeat ramp-up
Applies as from SW 3
300742 Lower limit violated MD POWER ON

300742 Converter frequency U/f POWER ON
Power On
Drive only ramps up to ramp-up state 2
In V/f mode (selection via MD 1014), only converter frequencies (MD 1100) of 4 kHz and 8 kHz are permissible.
Eliminate error during input of converter frequency MD 1100 or by deselecting V/f mode MD 1014.
Applies as from SW 5.1
300743 Error on saving FEPROM POWER ON
POWER ON
Drive only ramps up to ramp-up state 2
Error occurred when last saved; data from last save operation are used.
Additional information: none
S Check parameters and save BOOT again
Applies for SW 3 only
