When the "VA mode selection" parameter is set to "2: Speed at feedback position & command position
(only internal profile)
When the motor feedback speed falls in the setting range of the "VA detection speed range" parameter with the
target speed as a center, the VA output is turned ON.

z TRQ-LMTD output
This signal is enabled when the torque limiting is being performed. When the motor output torque reaches the torque
limiting value, the TRQ-LMTD output is turned ON. Refer to p.112 for the torque limiting function.
z SPD-LMTD output
This signal is enabled when the speed limiting is being performed. If the operating speed increases equal to or higher
than the value set in the "SPD-LMT speed limit ratio" parameter or the "SPD-LMT speed limit value" parameter, it is
limited to turn the SPD-LMTD output ON.

Description
Selects the judgment criterion of the VA
output.
Sets the allowable range of the judgment
criterion for the feedback speed when the
"VA mode selection" parameter is set to "0:
Feedback speed attainment (speed at
feedback position)" or "2: Speed at
feedback position & command position
(only internal profile)."
Selects the setting method of the speed
limit value.
Sets the percentage of the speed limit
based on "Speed" of the operation data
being 100 %. This is enabled when the
"SPD-LMT speed limit type selection"
parameter is set to "0: Ratio."
Sets the speed limit value as "Value." This is
enabled when the "SPD-LMT speed limit
type selection" parameter is set to "1:
Value."
