Panasonic MINAS-A5B Series - Velocity Control; Attained Speed Output (AT-SPEED)

No. SX-DSV02472 -38-
4-3 Velocity Control
Carried out the speed control based on the speed command object EtherCAT communication which is input from the
host controller.
This describe the basic configuration when using the speed control.
As the speed control mode, there is a Profile velocity control(pv) and Cyclic synchronous velocity control(csv).
For details, refer to Technical Reference, SX-DSV02473”Section 6-7”, EtherCAT communication specification.
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”.

At-speed
(Speed arrival)
10–20000 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.
