Motor parameters
Use this parameter group to adjust the inverter to the motor.
30_ / 31_
Limits 1 / 2
300 / 310
Start/stop speed 1 / 2
Setting range 0 ... 150 [rpm]
If the setpoint speed is higher than the start/stop speed, the drive will be
enabled with the start/stop speed. The transition to the setpoint speed is made
using the active speed ramp. If the setpoint speed is lower than the start/stop
speed, the setpoint will become active immediately.
In the VFC & hoist operating mode, the drive is always enabled with the rated
motor slip speed.
During startup, the start/stop speed is set to half the rated slip speed of the
connected motor.
When a stop command is performed, this setting also defines the slowest speed
at which the motor energization is switched off or at which post-magnetization
takes effect and the brake is applied.
301 / 311
Minimum speed 1 / 2
Setting range 0 ...
15
... 5500 [rpm]
Speed value, the lower limit of which must not be exceeded even when zero is
selected as the setpoint. The minimum speed also applies when n
min
< n
start/
stop
has been set.
Caution:
•
The slowest speed is 15 rpm when the hoist function is active, even if
n
min
has been set to a lower value.
•
To also enable the drive to move clear of the limit switches at low
speeds, n
min
is not active when drive has contacted the hardware limit
switch.
302 / 312
Maximum speed 1 / 2
Setting range 0 ...
1500
... 5500 [rpm]
No setpoint greater than the value set here can be selected. If you set n
min
> n
max
, then the value set in n
max
applies to the minimum speed and the
maximum speed.
In the VFC and VFC + DC BRAKING operating mode, you may enter the
following maximum speed values depending on the number of poles:
•
2-pole: max. 5500 rpm
•
4-pole: max. 4000 rpm
•
6-pole: max. 2600 rpm
•
8-pole: max. 2000 rpm
Fault 08
Speed monitoring
may appear if you enter higher values.
When you perform a startup, the unit automatically sets the maximum
speed to the transition speed.
No.
