Changeover threshold C0988 Set C0988 in accordance with the mains voltage:
AC 230 V
ð C0988 = 112 %
AC 400 V
ð C0988 = 112 %
AC 440 V
ð C0988 = 123 %
AC 460 V
ð C0988 = 129 %
AC 480 V
ð C0988 = 134 %
AC 500 V
ð C0988 = 140 %
V/F-rated frequency C0015 A value adapted to the drive, e.g. 50 Hz Depending on the drive power up to min. 25% of the
value under C0015 in parameter set 1:
• Rule of thumb: 2.2 kW ð 50 %
• Decrease for lower drive power, increase for
higher drive power.
When operating with parameter set 2 the energy of
motor will be reduced by overexcitation.

min
boost C0016 A value adapted to the drive, e.g. 5 % Depending on t he drive power up to 500% of the
value under C0016 in parameter set 1:
• Rule of thumb: 2.2 kW ð factor 3
• Increase the factor for lower drive power,
decrease the factor for higher drive power.
When operating with parameter set 2 the energy of
the motor will be reduced by overexcitation even in
the lower speed range.
Deceleration time for quick stop when
braking along the quick stop ramp:
C0105 Braking time required for AC braking Deceleration time of the drive with max. inertia load

deceleration
The higher the mainsvoltage the longer the deceleration time for AC braking must
be set in parameterset 1to perform the ACmotor braking. For this reasonbraking
times with the DC injection brake are shorter at mains voltages > 400 V.
