1-71 Start Delay
Range:
0 s* [0.0 - 120.0 s]
1-72 Start Function
Option:
[0] DC Hold/Motor Preheat
[1] DC Brake
[2] * Coast
Function:
Enter the % value to compensate voltage in relation to load when the motor is running at high speed
and obtain the optimum U/f characteristic. The motor size determines the frequency range within
which this parameter is active.
Motor size
0.25 kW - 7.5 kW
11 kW - 45 kW
55 kW - 550 kW
Function:
Enter the % value for slip compensation, to compensate for tolerances in the value of n
compensation is calculated automatically, i.e. on the basis of the rated motor speed n
Function:
Enter the slip compensation reaction speed. A high value results in slow reaction, and a low value
results in quick reaction. If low-frequency resonance problems arise, use a longer time setting.
Function:
Enter the resonance dampening value. Set par.1-64
Dampening Time Constant
to help eliminate high-frequency resonance problems. To reduce reso-
nance oscillation, increase the value of par.1-64
Function:
Resonance Dampening
Set par.1-64
eliminate high-frequency resonance problems. Enter the time constant that provides the best damp-
ening.
Function:
This parameter refers to the start function selected in par. 1-72
Enter the time delay required before commencing acceleration.
The parameter is also used for delayed start of compressor functionality in Injection Control. Pa-

set then delayed start is activated. If parameter 28-91 is reset then delayed start is deactivated. It
is recommended that the start delay value should be set equal to or greater than default value.
Function:
Select the start function during start delay. This parameter is linked to par. 1-71
Energizes motor with a DC holding current (par. 2-00) during the start delay time.
Energizes motor with a DC braking current (par. 2-01) during the start delay time.
Releases shaft coasted converter during the start delay time (inverter off).
