11 SUB FUNCTIONS
(2) When "0" is set in " Pr. 6 Bias speed at start", making a speed change with
the setting of "0" in " Cd. 7 New speed value" results in the following.
•
A deceleration stop is made and 0 speed (Md. 7 Status: b2) turns ON.
•
The axis stops but "Md. 4 Axis operation status" is "Speed.Position
Speed" or "JOG Operation" and the BUSY signal remains ON. (When the
axis stop signal is turned ON, the BUSY signal turns OFF and "Md. 4 Axis
operation status" changes to "Stopped".)
In this case, making a speed change with the setting of other than "0" in
" Cd. 7 New speed value" and "1" in " Cd. 6 Speed change request" turns
OFF 0 speed (Md. 7 Status: b2), enabling operation to be continued.

(3) A speed change cannot be made during the following deceleration. (The
speed change request is ignored.)
•
During deceleration started by turning ON the axis stop signal
•
During deceleration started by turning OFF the JOG start signal
(4) If the speed change request is made during position control of speed-
position switching control or during OPR control, the "Speed change not
possible" warning (warning code: 22) occurs and a speed change cannot be
made.
(5) If the value set in " Cd. 7 New speed value" is equal to or higher than " Pr. 5
Speed limit value", the "Outside speed" warning (warning code: 20) occurs
and the speed is controlled at " Pr. 5 Speed limit value".
If the value set in " Cd. 7 New speed value" is lower than " Pr. 6 Bias speed
at start", the "Outside speed" warning (warning code: 20) occurs and the
speed is controlled at " Pr. 6 Bias speed at start".
