P-03
Motor Rated Frequency
Range:
25 to 500 Hz
Preset:
60 Hz (Display shows
)
Rated frequency of the motor (listed on the nameplate). Adjusting the Voltage /
Frequency (V/F)
If motor instability is experienced, increase or decrease the voltage (P-37) at the
speed of instability (P-36).

P-04
Motor Rated Speed
Range:
0, 360 to 30000 RPM
Preset:
0
The RPM rated speed of the motor (listed on the motor nameplate). When set to
a value other than 0, all speed related parameters are displayed in RPM.
P-05
Minimum Output Speed
Range:
0 to P-06 (max 500 Hz)
Preset:
0
Limits the speed reference to the drive regardless of the speed reference
supplied to the drive.
Note: When P-04 is set to a value other than “0”, the value displayed will be
in RPM.
P-06
Maximum Output Speed
Range:
P-05 to 5 times P-03 (max 500Hz)
Preset:
60.0
User specified maximum motor speed, speeds greater than this are not allowed.
Note: When P-04 is set to a value other than “0”, the value displayed will be
in RPM.
P-07
Start/Stop Source
Range:
0 to 6
Preset:
0
0 - Terminal Strip
Speed and other commands are from the terminal strip.
1: Keypad control (forward only)
Uni-directional control from the keypad (up down arrows are used to change
the speed reference).
The drive must be enabled (control terminals 1 & 2
connected).
2: Keypad control (forward and reverse)
Bi-directional control from the keypad. START changes between forward
and reverse,
and
change speed).
The drive must be enabled (control
terminals 1 and 2 connected).
3: MODBUS
Network control using internal accel / decel ramps.
4: MODBUS
Network control with accel / decel ramp adjustment via modbus.
5: User PI control with external feedback signal.
6: User PI control with analog input 1 summation.
Sets the input source for Speed, Start/Stop and other commands.
