P020 Speed Ramps 3 and 4: Time Unit of Measure
P020 Range
0 ÷ 3
0 → 0.01 s
1→ 0.1 s
2→ 1 s
3→ 10 s
Default
See Table 82 and Table 86
Level
ADVANCED
Address
620
Function
Defines the unit of measure for the times for speed ramp 3, P015 and P016,
and speed ramp 4, P020 and P018
. The allowable programmable range may
be extended from 0 s to 327000s.
P021 Selection for Ramp Rounding Off
P021 Range
0000b ÷ 1111b binary
0x0000 ÷ 0x000F hexadecimal
0 ÷ 15
0000b (no S ramps)
1111b (all S ramps)
Default
1111b (all S ramps)

Function
In this parameter, you can select the bit corresponding to the ramp to be rounded
off.
Example:
P021 = 0011b = 3 decimal → ramps 1 and 2 are rounded off.
The ramp rounding off all
ows reaching the reference end value with a zero tangent,
both while accelerating and while decelerating, thus suppressing torque peaks that
could damage mechanical couplings.
P022 Acceleration Ramp: Start Rounding Off Time
P022
Range
0 ÷ 100
0 ÷ 100 %
Default
See Table 82 and Table 86
Level
ADVANCED
Address
622
Function
Sets the rounding off time period for the first stage of the acceleration ramp. This
parameter
is expressed as a percentage of the acceleration ramp time of the active
ramp.
Example: the second ramp is active with an acceleration ramp time of 5 secs
, P022 =
50%. Therefore, reference acceleration is limited for the first 2.5 secs
of the ramp
time.
NOTE
When using parameter P022
, the preset acceleration ramp time is increased by:
(P022%)/2.
P023 Acceleration Ramp: End Rounding Off Time
P023
Range
0 ÷ 100
0 ÷ 100 %
Default
See Table 82 and Table 86
Level
ADVANCED
Address
623
Function
Sets the rounding off time period for the end stage of the acceleration ramp. This
parameter is expressed as a percentage of the acceleration ramp time of the active
ramp.
NOTE When using parameter P023, the preset acceleration ramp time is increased by: (P023%)/2.
