Setting Notes
(Default)
00.0 – Sets the minimum selectable operating frequency. This is temporarily
399 overridden while starting or stopping the motor.
The jog frequency may also be set below P07.
Notes: (1) With Tacho Mode (P30) = 001 or 003, the inverter will
stop under closed loop control until P37 < P07 + 0.5 Hz.
(2) When the inverter ramps down due to current overload,
it will trip with F00 when the output frequency reaches
P07.
(00.1)
00.1 – Sets the required maximum frequency limit. Note that the setting of this
400 parameter will affect the scaling of the analogue control input (P04),
ramp rates P02 and P03, and the USS protocol's 100% frequency.
(50.0)
[60.0]
00.0 – This parameter sets the frequency to which the inverter will run at
400 startup when parameter P04 has been set to 003, 004, 005 or 006. This
value may be updated automatically during operation in certain
operating modes selected via P04.
(50.0)
[60.0]
080 – This parameter allows the output frequency at a given control voltage/
240 current input to be trimmed. Adjusting this parameter from 100(%) to
080(%) will reduce the frequency corresponding to an analogue input
voltage of 10 V (or 20 mA) by a factor of 0.8. Setting the parameter to
240(%) will increase the frequency by a factor of 2.4.
(100)
00.0 – Sets the dc injection voltage as a percentage of the mains voltage. The
20.0 optimum setting is dependent on motor type and inertia. Too high a
level will result in overcurrent and tripping of the drive (F00). Too low a
level will result in longer than necessary stopping times. DC injection
braking is enabled automatically when P11 is set to a non–zero value.
(00.0)
00.1 – Sets the inverter frequency reached when the jog control input is active.
400 Overrides the minimum frequency setting.
(05.0)
00.0 – Sets the amount of slip compensation (Hz) added to the output
20.0 frequency when a current equal to the current limit (set via P17) is
supplying the motor.
Note that excessive slip compensation will cause the motor to increase
speed above that equivalent to the original set output frequency and
overloading may result.
