Speed Control with Fixed Position Stop
Speed control with fixed position stop of the specified axis is executed.
Speed control with fixed position stop is started using the PVF (forward rotation) or PVR (reverse rotation) of servo program
instruction.
: Must be set,
: Set if required
*1 Only when the reference axis speed is specified
Processing details
• After starting of servomotor, control at the specified speed is executed until the fixed position stop command turns on.
• When the fixed position stop command turns on, a positioning control to the specified address is executed.
• It can be controlled in the axis which "control unit is [degree] and stroke limit is invalid ("upper stroke limit value" equal to
"lower stroke limit value")". If it is started for axis which "control unit is except [degree] or stroke limit is not invalid", a minor
error (error code: 19EAH) occurs and it does not start.
• Address setting range is 0 to 35999999 (0 to 359.99999 [degree]) in the indirect setting of positioning address. If it is set
outside the setting range, a minor error (error code: 1A31H) occurs and it does not start. Positioning address is input at the
program start.
