Frequency control:
Standard setpoint source
Network [5] The setpoint is dened as process data object via the network.
Frequency preset 1 ... 15 [11] ... [25]
For the setpoint selection, “preset” values can be parameterized and selected. All frequency presets are described in
detail in the commissioning manual.
0x2838:001 Start method
Normal [0] After start command, the standard ramps are active.
DC braking [1] After start command, the "DC braking" function is active for the time set in 0x2B84:002.
0x2838:003 Stop method
Coasting [0] The motor has no torque (coasts down to standstill).
Standard ramp [1]
The motor is brought to a standstill with deceleration time 1 (0x291D:002) or - if activated - with deceleration time 2
(0x291D:004).
Quick stop ramp [2] The motor is brought to a standstill with the deceleration time (0x291C) set for the "Quick stop" function.
0x2540:001 Rated mains voltage
230 Ve [0]
Selection of the mains voltage for actuating the inverter.400 Ve [1]
480 Ve [2]
0x2915 Minimum frequency 0.0 ... 599.0Hz Lower limit value for all frequency setpoints.
0x2916 Maximum frequency 0.0 ... 50.0 ... 599.0Hz Upper limit value for all frequency setpoints.
0x291D:001 Acceleration 1 0.0 ... 5.0 ... 3600.0s Acceleration time 1.
0x291D:002 Deceleration 1 0.0 ... 5.0 ... 3600.0s Deceleration time 1
0x2C00 Motor control type
Servo control (SC ASM) [2] This control mode is used for servo control of an asynchronous motor.
Sensorless vector control (SLVC) [4] This control mode 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 mode is used for the sensorless control of a synchronous motor.
0x2B00 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.
0x2B01:001 Base voltage 0 ... 400 ... 5000V *
Base voltage and base frequency dene 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.
0x2B01:002 Base frequency 0 ... 50 ... 1500 Hz
* Default setting dependent on the model
