Notes
P07 Minimum frequency (Hz) 00.0 –
399
(00.1)
Sets the minimum selectable operating frequency. This is temporarily
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.
P08 Maximum frequency (Hz) 00.1 –
400
(50.0)
[60.0]
Sets the required maximum frequency limit. Note that the setting of this
parameter will affect the scaling of the analogue control input (P04),
ramp rates P02 and P03, and the USS protocol’s 100% frequency.
P09 Digital frequency setpoint adjustment
(Hz)
00.0 –
400
(50.0)
[60.0]
This parameter sets the frequency to which the inverter will run at
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.
P10 • Analogue frequency setpoint
adjustment (%)
080 –
240
(100)
This parameter allows the output frequency at a given control voltage/
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.
P11 DC injection braking (%) 00.0 –
20.0
(00.0)
Sets the dc injection voltage as a percentage of the mains voltage. The
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.
P12 Jog (Hz) 00.1 –
400
(05.0)
Sets the inverter frequency reached when the jog control input is active.
Overrides the minimum frequency setting.
P13
• Slip compensation (Hz) 00.0 –
20.0
(00.0)
Sets the amount of slip compensation (Hz) added to the output
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.
