Function 5: Acceleration time ramp 1
TAB1
This parameter sets the time to accelerate the motor from 0 to 50 Hz.
Use the following formula to determine the proper time for other frequencies:

Function 7: Voltage/frequency ratio
TAB1
Sets the frequency (knee-point frequency) at which the maximum inverter output volt-
age is reached.
The maximum inverter output voltage depends on the mains voltage and on TAB2,
function MOD.
An incorrect setting of this parameter may lead to the damage
of the motor.
Range: 30...650 Hz
