Manual pulse generator speed limit mode
In "[Pr.122] Manual pulse generator speed limit mode", the output operation which exceeds "[Pr.123] Manual pulse generator
speed limit value" can be set during manual pulse generator operation.
The setting value and operation for "[Pr.122] Manual pulse generator speed limit mode" are shown below.
Setting Operation
value
0 The speed limit by "[Pr.123] Manual pulse generator speed limit value" is not executed.
[Pr.123]
Manual pulse

Output
1 The pulses which exceed "[Pr.123] Manual pulse generator speed limit value" are not output.

Output
2 The pulses which exceed "[Pr.123] Manual pulse generator speed limit value" are output later. The overcarrying movement amount which exceeds
"[Pr.123] Manual pulse generator speed limit value" can be checked in "[Md.62] Amount of the manual pulser driving carrying over movement" (-
2147483648 to 2147483647). When the movement amount which exceeds "[Pr.123] Manual pulse generator speed limit value" is generated
continuously and "[Md.62] Amount of the manual pulser driving carrying over movement" exceeds tolerance (-2147483648 to 2147483647), the
error "Overcarrying movement amount overflow in manual pulse generator" (error code: 1982H) occurs and a deceleration stop is executed.

Output
*1 When exceeding "[Pr.123] Manual pulse generator speed limit value", the input from the manual pulse generator is not the same as the
output from the Simple Motion module.
*2 When the pulses which exceed "[Pr.123] Manual pulse generator speed limit value" are large, it takes time between when the input from
the manual pulse generator stops and when the output from the Simple Motion module stops.
When "1: Don't output over value of speed limit" or "2: Output over value of speed limit later" is set in "[Pr.122] Manual pulse
generator speed limit mode", the warning "Outside manual pulse generator speed limit value" (warning code: 0989H) occurs
at exceeding "[Pr.123] Manual pulse generator speed limit value".
