Chapter 12 Inverter Functions
Forward/Reverse Drive Stop Function (FOT/ROT)
• Function to prevent the operation range from being
deviated using the signal from the control range limit
switch.
• The torque limit is restricted to 10% on the forward
rotation side when the 082[FOT] terminal is input and on
the reverse rotation side when the 083[ROT] terminal is
input. This is applicable as the limit switch at the edge of
the machine.
Position Range Designation Function
• Specify the position control range at the [AE-52] position
range designation (forward rotation side) /[AE-54]
position range designation (reverse rotation side).
• When the current position counter exceeds this setting,
there is a trip with the position control range error (E104)
and the inverter becomes the free-running status.
Position Memory at Power-Off
• By setting the [AE-61] current position memory at
power-off to 01, the current position data at
power-off can be stored.
• Use this for the application where the shaft of the
motor is locked at power-off.
• For the machine of which the shaft idles at
power-off, there is likely to be a gap between the
stored position and the current position when the
power is turned on again.
Position Data Preset
• When the 085[PSET] terminal is turned on, the
current position counter (can be monitored with
[dA-20]) is overwritten with the value set to the
[AE-62] preset position data.
• Available for restarting in the middle of the
positioning process, etc. (Data is overwritten at the
ON edge of the [PSET] terminal.)
