Deceleration time
(deceleration time)
P
0 ... 320.00 s
{ 2.00 }
Deceleration time the time corresponding to the linear frequency reduction from the set maximum
frequency to 0 Hz (P105). If a prevailing setpoint of <100% is used, the deceleration time
decreases accordingly.
Deceleration time can be extended by certain circumstances such as the selected >Switch-off
mode< (P108) or >Ramp rounding-off< (P106).
NOTE:
Make sure parameter values are realistic. A setting of P103 = 0 is not permissible for drive units!
Notes on ramp gradient: see parameter (P102)

Minimum frequency
(minimum frequency)
P
0.0 ... 400.0 Hz
{ 0.0 }
The minimum frequency is the frequency supplied by the VFD as soon as it is enabled and no
additional setpoint is set.
These are added to the set minimum frequency in combination with other setpoints (e.g. analog
setpoint or fixed frequencies).
This frequency is not reached when
a. the drive is accelerated from standstill.
b. the VFD is blocked. The frequency then decreases to the absolute minimum frequency
(P505) before it is blocked.
c. the VFD reverses. The rotating field reverses at the absolute minimum frequency (P505).
This frequency can be continuously not reached if the "Maintain Frequency" function (digital input
function = 9) is executed during acceleration or braking.

P105
Maximum frequency
(maximum frequency)
P
0.1 ... 400.0 Hz
{ 50.0 }
The frequency supplied by the VFD after being enabled and once the maximum setpoint is
present, e.g. analog setpoint corresponding to P403, an appropriate fixed frequency or maximum
via the Simple Box/Parameter Box.
This frequency can only be exceeded through slip compensation (P212), the "Maintain the freq."
function (digital input function = 9) or switching to another parameter set with a lower maximum
frequency.
Maximum frequencies are subject to certain restrictions, e.g.
• restrictions in the field weakening mode,
• compliance with mechanically permissible speeds,
• PMSM: maximum frequency restricted to a value that is slightly above the rated frequency.
This value is calculated from the motor data and the input voltage.
