P211.00 Max. frequency
Device for 50-Hz mains: 50 Hz *
Device for 60-Hz mains: 60 Hz *
Upper limit value for all frequency setpoints.
P220.00 Acceleration 1 0.0 ... 5.0 ... 3600.0s Acceleration time 1.
P221.00 Deceleration 1 0.0 ... 5.0 ... 3600.0s Deceleration time 1
P300.00 Motor ctrl mode
Servo control (SC ASM) [2] This control mode is used for servo control of an asynchronous motor.
Sensorless control (SL PSM) [3] This control type is used for the sensorless control of a synchronous motor.
Sensorless vector control (SLVC) [4] This control type is used for sensorless vector control of an asynchronous motor.
V/f characteristic control
VFC open loop
[6]
This control mode is used for the speed control of an asynchronous motor via a V/f characteristic and is the simplest
control mode.
V/f characteristic control
(VFC closed loop)
[7] The control mode is used for speed control of an asynchronous motor via a V/f characteristic with speed feedback.
Sensorless control (SLSM-PSM) [8] This control type is used for the sensorless control of a synchronous motor.
P302.00 V/f characteristic shape
Linear [0] Linear characteristic for drives with constant load torque over the speed.
Square-law [1] Square-law characteristic for drives with a square-law load torque over the speed.
Eco [3] Linear characteristic with energy optimization in the partial load operational range.
P303.01 Base voltage 0 ... 230 ... 5000V *
Base voltage and base frequency dene the V/f ratio and thus the gradient of the V/f characteristic.
• The V/f base voltage is usually set to the rated motor voltage.
• The V/f base frequency is usually set to the rated motor frequency.
P303.02 Base frequency
Device for 50-Hz mains: 50 Hz *
Device for 60-Hz mains: 60 Hz *
P304.00 Limitation of rotation
Only clockwise (CW) [0]
The motor can only be rotated clockwise (CW). The transfer of negative frequency and PID setpoints to the motor control
is prevented.
Both rotation directions [1] Both directions of motor rotation are enabled.
P305.00 Switching frequency 8kHz var/opt/4 * Selection of the inverter switching frequency.
P306.01 Overload selection
Heavy duty [0] Load characteristic for high dynamic requirements.
Light Duty [1] Load characteristic for low dynamic requirements.
P308.01 Max.load for 60s 30 ... 150 ... 200%
Maximum permissible thermal motor utilization (max. permissible motor current for 60 seconds). With regard to rated
motor current (P323.00).
P316.01 Fixed V/f boost 0.0 ... 2.5 ... 20.0% * Constant voltage boost for the V/f characteristic control without feedback.
P323.00 Rated. mot curr. 0.001 ... 1.700 ... 500.000A * Setting of the rated motor current according to motor nameplate.
P324.00 Max. current 0.0 ... 200.0 ... 3000.0 % Maximum overload current of the inverter. With regard to rated motor current (P323.00).
P400.01 Inverter enable TRUE [1]
Assignment of a trigger to the “inverter enable” function.
Trigger = TRUE: The inverter is enabled (unless there is another cause for inverter disable).
Trigger = FALSE: The inverter is disabled. The motor has no torque and coasts.
* Default setting dependent on the model
