Basic Functions
4-14
4.3.1 Attained speed output (AT-SPEED)
The AT-SPEED signal is output as the motor reaches the speed set to Pr 4.36 "Attained speed".

Class No. Attribute Title Range Unit Function
4 36 A At-speed
(Speed arrival)
10 to 20000 r/min Set the detection timing of the speed arrival output
(AT-SPEED).
When the motor speed exceeds this setup value, the
speed arrival output (AT-SPEED) is output.
Detection is associated with 10 r/min hysteresis.
4.3.2 Speed coincidence output (V-COIN)
This signal is output when the motor speed is equal to the velocity specified by the velocity command.
The motor speed is judged to be coincident with the specified speed when the difference from the velocity
command before/after acceleration/deceleration is within the range specified by Pr 4.35 “Speed
coincident range”.

Class No. Attribute Title Range Unit Function
4 35 A Speed coincidence
range 10 to
20000 r/min Set the speed coincidence (V-COIN) output detection timing.
Output the speed coincidence (V-COIN) when the difference
between the speed command and the motor speed is equal to
or smaller than the speed specified by this parameter.
The detection response has 10 r/min hysteresis.
*1 Because the speed coincidence detection is associated with 10 r/min hysteresis, actual detection range is as shown below.
- Speed coincidence output OFF to ON timing = (Pr 4.35
– 10) r/min
- Speed coincidence output ON to OFF timing = (Pr 4.35 + 10) r/min
