Motor cooling (enters the motor cooling system)
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
Motor overload factor (entry in % referred to P0305)
This defines the limit of the maximum output current as a % of the
rated motor current (P0305). This parameter is set, using P0205 for
constant torque, to 150 %, and for variable torque, to 110 %.
Selection of command source * (enters the command source)
0 Resets the digital I/O to the factory default setting
1 BOP (drive inverter keypad)
2 Terminal strip (factory default setting)
4 USS on BOP link
5 USS on COM link (via control terminals 29 and 30)
6 CB on COM link
Selection of frequency setpoint *
(enters the frequency setpoint source)
1 Motorized potentiometer setpoint (MOP setpoint)
2 Analog input (factory default setting)
3 Fixed frequency setpoint
4 USS on BOP link
5 USS on COM link (control terminals 29 and 30)
6 CB on COM link (CB = communications module)
7 Analog input 2
Min. frequency (enters the lowest motor frequency in Hz)
Enters the lowest motor frequency with which the motor operates
independently of the frequency setpoint. The value which is set here
applies for both directions of rotation.
Max. frequency (enters the highest motor frequency in Hz)
Enters the maximum frequency to which, for example, the motor is
limited independently of the frequency setpoint. The value which is set
here applies for both directions of rotation.
Ramp-up time (enters the ramp-up time in s)
Enters the time with which, for example, the motor should accelerate
from standstill up to the maximum frequency P1082. If a ramp-up time
is parameterized which is too low, then this can result in alarm A0501
(current limit value) or the drive inverter being shutdown with fault
F0001 (overcurrent).
Ramp-down time (enters the deceleration time in s)
Enters the time with which, for example, the motor should be braked
from the maximum frequency P1082 down to standstill. If the ramp-
down time is parameterized too low, then this can result in alarms
A0501 (current limit value), A0502 (overvoltage limit value) or the drive
inverter being powered-down with fault F0001 (overcurrent) or F0002
(overvoltage).
OFF 3 ramp-down time (enters the fast stop ramp-down time
in s)
Enters the time, for example, with which the motor should be braked
from the maximum frequency P1082 down to standstill for an OFF3
command (fast stop). If the ramp-down time is parameterized too low,
then this can result in alarms A0501 (current limit value), A0502
(overvoltage limit value) or the drive inverter being shutdown with fault
F0001 (overcurrent) or F0002 (overvoltage).
