Commissioning
5.5 Commissioning using the BOP
Control Units CU240S
60
Operating Instructions, 07/2008 - FW 3.2, A5E00766042B AD
Parameter Description
Setting
P0700 = 2
Selection of command source*
0: Factory default setting
1: BOP (keypad)
2: Terminal (Default for CU240S)
4: USS on RS232
5: USS on RS485
6: Fieldbus (Default for DP and PN variants)
P1000 = 2
Selection of frequency setpoint*
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 DP and PN variants)
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).
P1121 = … Ramp-down time
Enter the time (in seconds) in which the motor should decelerate (using braking) from the
maximum frequency P1082 down to standstill. If the ramp-down time is set too short, this can
cause alarm A0501 (current limit value) or A0502 (overvoltage limit value) or tripping the
inverter with fault F0001 (overcurrent) or F0002 (overvoltage).
P1300 = … Control mode*
0: V/f with linear characteristic (default)
1: V/f with FCC
2: V/f with parabolic characteristic
3: V/f with programmable characteristic
P3900 = … End quick commissioning (QC)*
0: No quick commissioning (no motor calculations, default)
1: Motor calculation and reset of all parameters that haven't been changed while QC process to factory
setting.
2: Motor calculation and reset of all I/O settings to factory settings.
3: Only motor calculation - other parameters are not reset.
Note: If P3900 = 1, 2, or 3 P0340 is set to 1 and the value from P1082 is written into P2000. The appropriate
motor data will be calculated.
While end of quick commissioning is performed "bUSY" will be displayed on the BOP. This means that the
control data are being calculated and the respective parameter values are stored in the EEPROM. After
quick commissioning has been completed, P3900 and P0010 will be set to 0. The actual frequency is
displayed.
