NOTE
1 The HOPSTP, HOPENB, and HOPEMG signals are valid
only when the HOPATH signal is 1.
2 Unless cables are connected correctly, correct signal values
cannot be output.
3 When the handy operator’s panel (Type B) is used, this
signal is ignored.
The deadman’s switch status is determined as follows:
(1)When the signals mentioned previously are in the following states,
both the deadman’s switches are released:
D HOPATH(F0208#0)=1
D HOPSTP(F0175#5)=0
D HOPENB(F0175#6)=1
D HOPEMG(F0175#7)=1
(2)When the signals mentioned previously are in the following states, at
least one deadman’s switch is pressed:
D HOPATH(F0208#0)=1
D HOPSTP(F0175#5)=0
D HOPENB(F0175#6)=1
D HOPEMG(F0175#7)=0
NOTE
1 If the HOPATH signal (F0208 #0) is 0 (the handy operator’s
panel is not connected), the deadman’s switch status
cannot be determined.
2 If the HOPSTP signal (F0175 #5) is 1 (the emergency stop
button on the handy operator’s panel is pressed), the
deadman’s switch status cannot be determined.
3 When the HOPENB signal (F0175 #6) is 0 (the deadman’s
switch enable switch on the handy operator’s panel is off),
the deadman’s switch status cannot be determined.
4 When the emergency stop state is set on a machine
operator’s panel connected to an upper unit of the handy
operator’s panel, or when another emergency stop contact
such as the door open limit switch is off, the deadman’s
switch status cannot be determined.
