Default Usage
Select the PM motor start mode.
[1] Parking
[0] Disabled Select [1] Enabled to enable the drive to catch a motor spin-
ning due to mains dropout. Select [0] Disabled if this function
is not required. When this parameter is set to [1] Enabled, pa-
rameter 1-71 Start Delay and parameter 1-72 Start Function are
not functional. Parameter 1-73 Flying Start is active in VVC+
mode only.
0 The minimum reference is the lowest value obtainable by
summing all references.
The maximum reference is the lowest obtainable by sum-
50
ming all references.
Size related If asynchronous motor is selected, the ramp-up time is from
0 to rated parameter 1-23 Motor Frequency. If PM motor is se-
lected, the ramp-up time is from 0 to parameter 1-25 Motor
Nominal Speed.
Size related For asynchronous motors, the ramp-down time is from rated
parameter 1-23 Motor Frequency to 0. For PM motors, the
ramp-down time is from parameter 1-25 Motor Nominal
Speed to 0.
0 Hz Enter the minimum limit for low speed.
Enter the maximum limit for high speed.
100 Hz
100 Hz Enter the maximum output frequency value. If parameter
4-19 Max Output Frequency is set lower than parameter 4-14
Motor Speed High Limit [Hz], parameter 4-14 Motor Speed High
Limit [Hz] is set equal to parameter 4-19 Max Output Frequen-
cy automatically.
[9] Alarm Select the function to control output relay 1.
[5] Drive run- Select the function to control output relay 2.
