Parameter Action/Description (Factory setting: bold)

Parameters with an "*" have more settings than listed below. Please refer to the parameter list

Your own

setting

2: 4-pole motor

Recalculated automatically when P0310 (rated motor frequency) or P0311 (rated motor speed)

is changed.

P0320 = ? Motor magnetizing current

Setting P0320 = 0 causes calculation according the setting of P0340 = 1 (data entered from

rating plate) or by P3900 = 1, 2 or 3.

The calculated value is displayed in parameter r0331.

P0335 = 0 Motor cooling

0: Self-cooled using shaft mounted fan attached to the motor

1: Force-cooled, using a separately powered cooling fan

2: Self-cooled and internal fan

3: Force-cooled and internal fan

P0400 = 0 Select encoder type

0: Disabled

2: Quadrature encoder no zero pulse

12: Quadrature encoder & zero pulse

Note: Encoders with zero pulse can also be connected, but the zero pulse is not used.

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)

P0610 = 2 Motor I2t temperature reaction

Defines reaction when motor temperature reaches warning threshold.

0: No reaction, warning only

1: Warning and Imax reduction

2: Warning and trip (F0011)

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 150 % and for light

overload, up to 110 %.

P0700 = 2 Selection of command source*

enter the command source

0: Factory default setting

1: OP (keypad)

2: Terminal (Default for CUS240S)

4: USS on RS232

5: USS on RS485

6: Fieldbus (Default for CUS240S DP and CUS240S 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)

1 ... 40 41 42 ... 110
