Remedy
• Set AL and AM values which make "Movement amount per
rotation (AL)" × "Unit magnification (AM)" within 2147483647,
and then turn the PLC READY signal [Y0] from OFF to ON.
• With the setting brought into the setting range, turn the PLC
READY signal [Y0] from OFF to ON.
• Set the bias speed to not more than the speed limit value.
• With the setting brought into the setting range, turn the PLC
READY signal [Y0] from OFF to ON.
"[Pr.2] Number of pulses per rotation (AP)",
"[Pr.3] Movement amount per rotation (AL)",
"[Pr.4] Unit magnification (AM)"
Review these parameters.
(Refer to Section 5.2.1)
• Set a value which is not less than the OPR speed.
• With the setting brought into the setting range, turn the PLC
READY signal [Y0] from OFF to ON.
With the setting brought into the setting range, turn the PLC
READY signal [Y0] from OFF to ON.
"[Pr.2] Number of pulses per rotation (AP)",
"[Pr.3] Movement amount per rotation (AL)",
"[Pr.4] Unit magnification (AM)"
"[Pr.11] Backlash compensation amount"
Review the items above.
(Refer to Section 5.2.1 or Section 5.2.3)
• Bring the setting into the setting range.
• In a unit other than "degree", set so that the lower limit value
is smaller than the upper limit value.
