(1) Alert output accumulated pulses and immediate stop accumulated pulses
Alert output accumulated pulses (accumulated pulses set to output an alert) and immediate stop accumulated
pulses (accumulated pulses set to stop the positioning immediately) are set by combining the following values.
• Reference value
• Alert output accumulated pulse setting value (
• Immediate stop accumulated pulse setting value (
• Accumulated pulse setting value selection
Cd.17
(2) If " Accumulated pulse setting value selection" is set to "0: Set with
Cd.17
pulse"
Alert output accumulated pulses and immediate stop accumulated pulses can be obtained as follows:
Alert output accumulated pulses = reference value + alert output accumulated pulse setting value
Immediate stop accumulated pulses = reference value + immediate stop accumulated pulse setting value
(a) When the value is outside the setting range
The accumulated pulse error detection function does not operate.
(b) Alert output accumulated pulse setting value and immediate stop accumulated
pulse setting value
The value of alert output accumulated pulses (maximum value) is calculated using the value of
" Immediate stop accumulated pulse setting value (maximum value)" at the following condition:
Cd.14
" Alert output accumulated pulse setting value (maximum value)" > "
Cd.13
pulse setting value (maximum value)"
The value of alert output accumulated pulses (minimum value) is calculated using the value of
" Immediate stop accumulated pulse setting value (minimum value)" at the following condition:
Cd.16
" Alert output accumulated pulse setting value (minimum value)" < "
Cd.15
pulse setting value (minimum value)"
When the setting values are as follows:
Ex.
• Alert output accumulated pulse setting value (maximum value): 1200
Cd.13
• Immediate stop accumulated pulse setting value (maximum value): 1100
Cd.14
Both alert output accumulated pulses and immediate stop accumulated pulses are judged by the
reference value + 1100 pulse. Thus, an alert is output and the positioning stops simultaneously.
