Explanation of the parameters
Parameters
P22x Synchro-
nous operation
control
Synchronous operation control is only possible with the "internal synchronous opera-
tion" technology function.
For a detailed description, see the “Internal Synchronous Operation“ manual.
P228 Feedforward
filter DRS
Setting range: 0 ... 100 ms
Setpoint filter for feedforward of internal synchronous operation. The master speed must
be filtered to achieve optimum acceleration feedforward of the slave drive. Filtering
requires the filter time constant. Value 0 indicates an unfiltered master speed.
P24x Synchro-
nous operation
with catch up
Synchronous operation with catch up is only possible in parameter set 1 with the "inter-
nal synchronous operation" technology function.
For a detailed description, see the “Internal Synchronous Operation“ manual.
When the slave drive is switched to synchronous operation, the current angle offset in
relation to the master is reduced to zero, depending on the operation mode selected.
For this catch up procedure to be performed in a controlled manner, it is possible to set
parameters for both the synchronization speed and the synchronization ramp.
P240 Synchroniza-
tion speed
Unit: [1/min]
Setting range: 0 ... 1500 ... 5000 1/min
This parameter indicates the duration of the synchronization procedure.
P241 Synchroniza-
tion ramp
Unit: [s]
Setting range: 0 ... 2 ... 50 s
Value of the acceleration ramp for synchronizing the slave with the master. A value of 0
means maximum possible acceleration.
P3xx Motor parameters
This parameter group is used to adjust the inverter to the motor. The parameters can be
set separately for parameter set 1 and 2. This means two different motors can be oper-
ated alternately on the same inverter without requiring a new setting.
P30x / P31x Limits 1 / 2
P300 / P310
Start/stop speed
1/2
Setting range: 0 ... 60 ... 150 1/min
Only effective in the VFC operating mode. The parameter has no function in CFC and
SERVO operating modes. This entry defines the smallest speed request which the
inverter sends to the motor when enabled. The transition to the speed determined in the
setpoint selection is made using the active acceleration ramp.
When a stop command is executed, this setting also determines the lowest speed at
which the motor power is switched off or the post-magnetization triggered and, if appli-
cable, the brake applied.
P301 / P311 Mini-
mum speed 1 / 2
Setting range: 0 ... 60 ... 5500 1/min
The speed value which lower limit 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.
Important:
•
The slowest speed is 15 1/min when the hoist function is active, even if n
min
has been
set to a lower value.
•
To enable the drive to move clear of the limit switches even at low speeds, n
min
is not
active for the hardware limit switch with which the drive has come into contact.
