9 REAL/VIRTUAL MODE SWITCHING AND STOP/RE-START
Check
sequence
• Is the feed current value within the stroke
limit range ?
1
• Is the feed current value within the range
of "[lower stroke limit value] to [stroke
amount]" ?
• Does not "[lower stroke limit value] +
2 [stroke amount]" exceed 2147483647
31
(2 -1) in the two-way cam mode ?
• When the clutch connected to between the
drive module and synchronous encoder is
"external input mode", are the clutch
ON/OFF device the same device ?
3
• When the clutch connected to between the
drive module and synchronous encoder is
"external input mode", are the encoder I/F
the manual pulse generator input ?
• Is the output module where either a "no
clutch" or "clutch ON command" in effect
for the virtual main shaft or the virtual
auxiliary input axis the servo ready
(M2415+20n : ON)?
4
• Is the external input signal "STOP" of
output module where either a "no clutch" or
"clutch ON command" in effect for the main
shaft or the auxiliary input axis OFF ?
• Can the current value within 1 cam
revolution be calculated in the two-way
5
cam mode ?
• Is the clutch ON/ OFF address setting
device for address mode clutch an even
6
number ?
(2) Output module check
(a) The items in Table 9.2 below are checked to determine the output module
state.
If an error is detected, it switches to the virtual mode, but the applicable
system cannot be started. Correct the error cause in the real mode, and
switch to virtual mode again.
(b) When an error is detected, the error detection signal (M2407+20n) of
applicable output module turns on, and the error code is stored in the
minor/major error code storage register.
