Keypad code Information
P100.00 Output frequency x.x Hz (read only) Display of the actual output frequency.
P103.00 Actual current x.x % (read only) Display of the actual motor current.
P106.00 Motor voltage x VAC (read only) Display of the actual motor voltage.
P150.00 Error code - (Read only) Error message.
P200.00 Control selection
Flexible I/O [0]
This selection enables a exible assignment of the start, stop, and rotating direction commands with digital signal
sources.
Keypad [1]
This selection enables the motor to start exclusively via the start key of the keypad. Other signal sources for starting the
motor are ignored.
P201.01 F-setp.source
Keypad [1] The setpoint is specied locally by the keypad.
Analog input 1 [2] The setpoint is dened as analog signal via the analog input 1.
Analog input 2 [3] The setpoint is dened as analog signal via the analog input 2.
HTL input [4]
The digital inputs DI3 and DI4 can be congured as HTL input to use an HTL encoder as setpoint encoder or dene the
setpoint as a reference frequency ("pulse train").
Network [5] The setpoint is dened 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.
P203.01 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 P704.02.
Flying restart circuit [2] After the start command, the ying restart circuit is active.
Premagnetization [3]
After start command, the standard ramps are active and the premagnetization of the motor is activated. This reduces the
motor current and smoothes the acceleration curve during the starting process (only relevant in the V/f motor control
mode).
P203.03 Stop method
Coasting [0] The motor has no torque (coasts down to standstill).
Standard ramp [1] The motor is brought to a standstill with the deceleration time 1 P221.00 (or deceleration time 2 P223.00 if activated).
Quick stop ramp [2] The motor is brought to a standstill with the deceleration time (P225.00) set for the "quick stop" function.
Switch-o positioning [3]
Is similar to the stop method “standard ramp [1]“. Depending on the actual output frequency, however, the inverter
delays the beginning of the down-ramping so that the number of motor revolutions until a standstill is reached and thus
the stop position is always relatively constant.
P208.01 Mains voltage
230 Ve [0]
Selection of the mains voltage for actuating the inverter.
400 Ve [1]
480 Ve [2]
120 Ve [3]
P210.00 Min. frequency 0.0 ... 599.0Hz Lower limit value for all frequency setpoints.
