3.3 - Explanation of parameters in
menu 1
: Speed reference selected
Adjustment range :± 1.06
Indicates the reference value.
: Pre-skip filter reference
Adjustment range :± 1.06 or 1.07 to 1.06
Reference after limiting but before the skips.
: Pre-ramp reference
Adjustment range :± 1.06 or 1.07 to 1.06
Indicates the reference after the skips but before the
acceleration or deceleration ramps.
: Reference offset
Adjustment range :± 1.06
Factory setting :0
This reference is added to (positive value) or subtracted from
(negative value) the selected reference if 1.09 equals 1
(OFFS). It can be used to correct the selected main reference
to obtain an accurate setting.
: Jog reference
Adjustment range :0 to 1.06 rpm
Factory setting :45 rpm
Operating speed when the jog input has been selected.
: Maximum reference clamp
Adjustment range :0 to 32000 rpm
Factory setting :Eur = 1500 rpm
USA = 1800 rpm
• Before setting the maximum reference clamp,
check that the motor and the driven machine can
withstand it.
Maximum speed in both directions of rotation.
: Minimum reference clamp
Adjustment range :0 to 1.06
Factory setting :0
In unipolar mode, defines the minimum speed.
WARNING:
• This parameter is inactive during jog operation.
• If the value of 1.06 is lower than that of 1.07, the value
of 1.07 is automatically changed to the new value of
1.06.
: Not used
: Reference offset validation
Adjustment range :0 or 1
Factory setting :0
0 (Ref x 01.38) (ProP): A value proportional to this
reference is added to the main reference. The percentage
is adjusted using the parameter 1.38.
1 (Ref + 01.04) (OFFS): A fixed value set in 1.04 is added
to the main reference.
: Bipolar reference select
Adjustment range :0 or 1
Factory setting :0
0 (+ only ref) (PoS): All negative references are treated as
invalid.
1 (+ and - ref) (nEg): Used for changing the direction of
rotation by the reference polarity. May come from the preset
references.
Note: The drive analog inputs are unipolar.
: Reference enable indicator
Adjustment range :0 or 1
Used to control enabling of the run command.
0 (Disabled) (StoP): Stop.
1 (Enabled) (run): Run.
: Reverse select indicator
Adjustment range :0 or 1
Used to control enabling of the direction of rotation.
0 (Forward) (Fd): Forward.
1 (Reverse) (rS): Reverse.
: Jog select indicator
Adjustment range :0 or 1
Used to control enabling of the jog command.
0 (Disabled) (OFF): Jog operation not enabled.
1 (Enabled) (Jog): Jog operation enabled.
: Reference selector
Adjustment range :0 to 4
Factory setting :0
0 (Term. inputs) (SEL): The speed reference is selected by
combining the digital inputs assigned to parameters 1.41 and
1.42.
1 (Analog 1) (Ana1): The speed reference comes from
analog input 1.
2 (Analog 2) (Ana2): The speed reference comes from
analog input 2.
3 (Preset) (Pr): The speed reference comes from the preset
references.
4 (Keypad) (Pad): The speed reference comes from the
local control or the LCD keypad.
