4.2.5.6 PNU 1786: deceleration time
This parameter defines the total time or rate (depending on the type of units selected for deceler-
ation) to reduce the velocity to 0 at the target position.
4.2.5.7 PNU 1787: deceleration jolt limiting
This parameter defines the form of the braking/deceleration ramp.
If a value
¹ 0 is entered here, then a sin²-ramp (S-curve) is used for braking/deceleration.
4.2.5.8 PNU 1788: next motion task
The motion task number of the motion task to be started can be from 1 to 180 (motion tasks in
EEPROM) or 192 to 255 (motion tasks in RAM).
4.2.5.9 PNU 1789: start delay
This parameter is used to set a delay time before the start of a motion task.
4.2.5.10 PNU 1310: copy motion task
This parameter can be used to copy motion tasks. The source motion task must be entered in the
high-value portion of PWE (PZD 5 & 6) and the target motion task must be entered in the low-value
portion of PWE (PZD 7 & 8).
4.2.5.11 PNU 1311: position, 32 bit floating decimal point format
With this object the target position for motion task 0 (direct motion task, see ASCII – command
O_P) can be set in 32 Bit Floating decimal point format (IEEE).
Right of decimal point positions will be truncated. This objekt is, aside from the data format, identi-
cal PNU 1790. The defaults are indicated in micrometers.
Use:
Controls that support only 16 Bit integer and 32 Bit floating decimal point.
4.2.5.12 PNU 1312: velocity, 32 bit floating decimal point format
With this object the velocity for motion task 0 (direct motion task, see ASCII – command O_V) can
be set in 32 Bit Floating decimal point format (IEEE).
Right of decimal point positions will be truncated. This objekt is, aside from the data format, identi-
cal PNU 1791.
Use:
Controls that support only 16 Bit integer and 32 Bit floating decimal point.
