Parameter Description (Parameter name and factory setting (if not variable) in bold)
P0408 = ? Encoder pulses per revolution
Specifies the number of encoder pulses per revolution (encoder resolution)
Note: The encoder resolution is limited by the max. pulse frequency of the encoder circuits
(f_max = 300 kHz).
P0500 = 0 Technological application
Selects technological application
0: High overload
1: Light overload (for pumps and fans, etc. sets internally P1300 = 2)
P0625 = ? Ambient motor temperature
Ambient temperature of motor at time of motor data identification.
Note: It is only allowed to change the value when the motor is cold. A motor identification has
to be made after changing the value.
P0640=150 Motor overload factor
Defines motor overload current limit [%] relative to P0305 (rated motor current).
This defines the limit of the maximum output current as a percentage of the rated motor
current (P0305). This parameter is set, using P0205 for high overload, to 200 % and for light
overload, up to 150 %.
P0700 = 2 Selection of command source*
enter the command source
0: Factory default setting
1: OP (keypad)
2: Terminal (Default for CU240S)
4: USS on RS232
5: USS on RS485
6: Fieldbus (Default for CU240S DP and CU240S DP-F)
P0727 = 0 Selection of 2-/3-wire method
Determines the control method using the terminals.
0: Siemens (start/dir)
1: 2-wire(fwd/rev)
2: 3-wire(fwd/rev)
3: 3-wire(start/dir)
P1000 = 2 Selection of frequency setpoint*
enter the frequency setpoint source
0: No main setpoint
1: MOP setpoint
2: Analog setpoint (Default for CU240S)
3: Fixed frequency
4: USS on RS232
5: USS on RS485
6: Fieldbus (Default for CU240S DP and CU240S DP-F)
7: Analog setpoint 2
P1080 = ? Minimum frequency
Enter the lowest motor frequency (in Hz) to which the motor operates independently of the
frequency setpoint. The value set here is valid for both clockwise and anticlockwise rotation.
P1082 = ? Maximum frequency
Enter the maximum frequency (in Hz) to which the motor is limited independently of the
frequency setpoint. The value set here is valid for both clockwise and anticlockwise rotation.
P1120 = ? Ramp-up time
Enter the time (in seconds) in which the motor should accelerate from standstill up to
maximum motor frequency P1082. If the ramp-up time is set too short, this can cause alarm
A0501 (current limit value) or tripping the inverter with fault F0001(overcurrent).
