[3] Speed control mode
Operation for speed control mode
The speed control is executed at the speed set in "
Cd.140
Command speed at speed
control mode
" in the speed control mode. Set a positive value for forward rotation
and a negative value for reverse rotation. "
Cd.140
" can be changed any time
during the speed control mode.
Acceleration/deceleration is performed based on a trapezoidal
acceleration/deceleration processing. Set acceleration/deceleration time toward
"
Pr.8
Speed limit value
" in "
Cd.141
Acceleration time at speed control mode
" and
"
Cd.142
Deceleration time at speed control mode
". The value at speed control mode
switching request is valid for "
Cd.141
" and "
Cd.142
".
The command speed during the speed control mode is limited with "
Pr.8
Speed
limit value
". If the speed exceeding the speed limit value is set, the warning "Speed
limit value over" (warning code: 501) occurs, and the operation is controlled with
the speed limit value.
Confirm the command speed to servo amplifier with "
Md.122
Speed during
command
".

If the current feed value exceeds the software stroke limit, the error "Software
stroke limit +" (error code: 507) or "Software stroke limit -" (error code: 508) occurs
and the operation switches to the position control mode. Invalidate the software
stroke limit to execute one-way feed.
