Notice: P1124 does not have any impact when JOG mode is selected. In this case, jog ramp times (P1060,
P1061) will be used all the time. If the Dual Ramp function is selected using P1175, ramp times will switch
between normal (P1120, P1121) and JOG (P1060, P1061) ramp times, depending on the settings of
P2150, P2157 and P2159. Therefore, it is not recommended that JOG ramp is selected at the same time
as Dual Ramp.
See P1120
P1130[0...2] Ramp-up initial rounding
time [s]
0.00 -
40.00
0.00 U, T - DDS Float 2
Defines rounding time in seconds at start of ramp-up.
Notice: Rounding times are recommended, since they prevent an abrupt response, thus avoiding detrimental
effects on the mechanics.
Rounding times are not recommended when analog inputs are used, since they would result in overshoot /
undershoot in the inverter response.
Note: If short or zero ramp times (P1120, P1121 < P1130, P1131, P1132, P1133) are set, the total ramp up time
(t_up) or ramp down time (t_down) will not depend on P1130.
P1131[0...2] Ramp-up final rounding
time [s]
0.00 -
40.00
0.00 U, T - DDS Float 2
Defines rounding time at end of ramp-up.
Notice: See P1130
P1132[0...2] Ramp-down initial
rounding time [s]
0.00 -
40.00
0.00 U, T - DDS Float 2
Defines rounding time at start of ramp-down.
Notice: See P1130
P1133[0...2] Ramp-down final
rounding time [s]
0.00 -
40.00
0.00 U, T - DDS Float 2
Defines rounding time at end of ramp-down.
Notice: See P1130
P1134[0...2] Rounding type 0 - 1 0 U, T - DDS U16 2
Defines the smoothing which is active by setpoint modifications during acceleration or deceleration (e.g.
new setpoint, OFF1, OFF3, REV). This smoothing is applied, if the motor is ramped-up or ramped-down
and
• P1134 = 0,
•
P1132 > 0, P1133 > 0 and
• the setpoint is not yet reached.
0 Continuous smoothing
1 Discontinuous smoothing
Dependency: Effect only when P1130 (Ramp-up initial rounding time) or P1131 (Ramp-up final rounding time) or P1132
(Ramp-down initial rounding time) or P1133 (Ramp-down final rounding time) > 0 s.
P1135[0...2] OFF3 ramp-down time
[s]
0.00 -
650.00
5.00 C(1), U, T - DDS Float 2
Defines ramp-down time from maximum frequency to standstill for OFF3 command. Settings in P1130 and
P1134 will have no effect on OFF3 ramp-down characteristic. An initial ramp-down rounding time of
approximately 10% of P1135 is however included. For the total OFF3 ramp-down time: t_down,OFF3 =
f(P1134) = 1.1 * P1135 * (|f_2| / P1082)
Note: This time may be exceeded if the Vdc_max level is reached.
