(g) Speed change and "out of setting range" error
If an "Outside the acceleration/deceleration time setting" error (Axis 1 error code: 1502) or "Deceleration stop
time out of range" error (Axis 1 error code: 1503) occurs at the start of speed change, the Axis 1 axis operation
status (SD1844) changes to Error occurring (-1). When each control is active, the following operations are
performed according to the control.
• In position control (including it of speed/position switching control)
Position control continues until the end and the axis decelerates to a stop over the deceleration stop time
effective before the speed change.
• In speed control
The axis decelerates to a stop over the deceleration stop time effective before the speed change.
• In JOG operation
The axis decelerates to a stop over the JOG deceleration time effective before the speed change or
DEC/STOP time at speed change (if the last speed change was successful).
The DEC/STOP time at speed change represents the "time until the axis stops at the new speed value" and not the "time
until the axis stops at the current speed."
