Parameters
11.7 Travel characteristic
P141 Suppress opposite direction
In manual mode, until this percentage value of the maximum velocity is reached, the drive is
only moved in the direction specified by the crane driver.
Default: 20 [%]
Access code: 0
P142 Factor for braking deceleration of trolley when countering (MAN)
If the sign of set velocity and actual velocity is different (countering), the set deceleration
resulting from P6 * P8 * P142 is operative in manual (MAN) mode. This parameter is only
operative when the SC_ON control bit is set and the conventional control method (P152) has
been selected (not for time-optimized). See also P8.
Default: 1.2
Access code: 1
P143 Acceleration reduction, precision travel
If the set velocity and the actual velocity equal less than 30% of the maximum velocity, the set
acceleration is multiplied by this factor. This parameter is only operative for the trolley when the
SC_ON bit is set, when the conventional control method has been selected (not for time-
optimized) and only for manual mode (MAN).
Default: 0.5
Access code: 2
P144 Deceleration reduction, precision travel
If the set velocity and the actual velocity are less than 30% of the maximum velocity, the set
acceleration is multiplied by this factor and used as the set deceleration value. The parameter
is only operative in manual mode (MAN) and only applies to the trolley. The parameter does not
act for time-optimized travel or when sway control is OFF.
Default: 0.5
Access code: 2
P145 Variable acceleration for the time-optimized control
A variable acceleration range can be specified for the time-optimized control. The controller
tries to vary the acceleration in such a way that simple ramps result. The acceleration is then
in the range (100% - P145) · P7 ... (100% + P145) · P7 or P5.
Default: 10 [%]
