Zone Data Area Section 4-8
• Set the time required to reach the maximum speed from the initial speed
of each axis.
• Set the time required to reach the target speed from the initial speed of
each axis.
4-8 Zone Data Area
The zone data area is used to make zone settings for the present positions of
the axes controlled by the PCU.
By setting zone data to the PCU’s internal memory, it is possible to monitor
whether the present positions for the axes are within the set zones using the
Zone Monitor Flags in the operating memory area.
Zone data settings can be saved to the CPU’s flash memory.
4-8-1 Zone Function
The zone function is used to notify the CPU Unit whether or not the position of
the machine being controlled by the PCU is within a set region. Notification is
made to the CPU Unit using the Zone Monitor Flags.
This function is mainly used when performing interlocks with peripheral
devices or simultaneous control, in response to the present position of the
machine.
There are 3 Zone Monitor Flags for each axis. The zones that are monitored
using these flags can be set separately (i.e., zones 0, 1, and 2). To use the
zone function, it is necessary to set both a CW-side value and a CCW-side
value for each zone used, as shown in the following diagram. These values
are the “zone data.” Once the settings have been made, operation will pro-
ceed in the following way, regardless of whether an origin has been estab-
lished or not.
Zone Monitor Flag ON (1): CCW-side value
≤
Present position
≤
CW-side
value
Zone Monitor Flag OFF (0): Any status other than the above.
If the zone function is not required, set the zone data so that the following is
satisfied:
CCW-side value
≥
CW-side value
For example, setting both the CCW-side value and the CW-side value to 0
would be sufficient to disable the zone function.
