4. Operation
4.2 Operation in Positioner Mode
4-76
ME0342-4B
(1) For Standard (PIO Pattern 4)
■ Control method
Load Output Judgment Status (LOAD) Signal
(Note 1)
turns ON when the pressing current exceeds
the value [%] set as the “threshold” of the position data in the pressing operation range (except
for approach operation range) and in the range set as the “position zone” in the position data for
the duration of judgment time
(Note 2)
or longer. It will not turn OFF even if the load has been
removed and the current has dropped. It turns OFF at next movement command or alarm reset.
Torque Level Status (TRQS) Signal
(Note 1)
turns ON when the pressing current exceeds the
value [%] set as the “threshold” of the position data in the pressing operation range (except for
approach operation range) for the duration of judgment time
(Note 2)
or longer. It turns OFF once it
has been confirmed that the load has been removed and the current has dropped.
● Condition
(Accumulated Time of Pressing Force Reaching Threshold Setting)
– (Accumulated Time of Pressing Force Staying at Threshold Setting or Below)
≥ 255ms (Pattern No.50)
Note 1 It should be switched to LOAD Signal with “0” set in Parameter No. 51
“Torque inspected range” and TRQS Signal with “1” set in the parameter.
Note 2 Establish the setting in Parameter No.50 “Load Output Judgment Time.”
(Initial setting: 255ms)
4.2 Operation in Positioner Mode
ME0342-4B 4-77
(2) Torque Level Detection During Pressing Operation (Enabled with PIO Pattern 7)
■ Control method
The pressing force set in percent [%] in "Threshold" of the position data should be monitored, and
when the pressing force satisfies the following condition, the torque level status (TRQS) signal
gets turned on. At that time, if the actuator is in the position zone, the load output judgment
(LOAD) signal also turns on.
This signal turns off when a movement command to another position gets issued or the servo
gets turned off. This signal keeps on until the next movement command is issued once it gets
turned on.
● Condition
(Accumulated Time of Pressing Force Reaching Threshold Setting)
– (Accumulated Time of Pressing Force Staying at Threshold Setting or Below)
≥ 255ms (Pattern No.50)
110ms+5ms+10ms-5ms+135ms ≥ 255ms
