Default
Usage
Parameter 1-70
PM Start Mode
[0] Rotor Detection
[1] Parking
[3] Rotor Last Position
[1] Parking
Select the PM motor start mode.
Parameter 1-73
Flying Start
[0] Disabled
[1] Enabled
[0] Disabled
Select [1] Enabled to enable the drive to catch a motor spin-
ning due to mains drop-out. Select [0] Disabled if this func-
tion is not required. When this parameter is set to [1] Ena-
bled, parameter 1-71 Start Delay and parameter 1-72 Start
Function are not functional. Parameter 1-73 Flying Start is ac-
tive in VVC
+
mode only.
Parameter 3-02
Minimum Refer-
ence
-4999.000–4999.000
0
The minimum reference is the lowest value obtainable by
summing all references.
Parameter 3-03
Maximum Ref-
erence
-4999.000–4999.000
50
The maximum reference is the lowest obtainable by sum-
ming all references.
Parameter 3-41
Ramp 1 Ramp
Up Time
0.01–3600.00 s
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.
Parameter 3-42
Ramp 1 Ramp
Down Time
0.01–3600.00 s
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.
Parameter 4-12
Motor Speed
Low Limit [Hz]
0.0–400.0 Hz
0 Hz
Enter the minimum limit for low speed.
Parameter 4-14
Motor Speed
High Limit [Hz]
0.0–400.0 Hz
100 Hz
Enter the maximum limit for high speed.
Parameter 4-19
Max Output
Frequency
0.0–400.0 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.

0.00–10.00 V
10 V
Enter the voltage that corresponds to the high reference val-
ue.
Parameter 6-12
Terminal 53
Low Current
0.00–20.00 mA
4 mA
Enter the current that corresponds to the low reference val-
ue.
