Note
• When setting the operation speed to 0, the work piece decelerates to stop, but the variable speed
operation does not end.
The operation pattern should be changed to another pattern when terminating the variable speed
operation.
• At STOP command ON, the work piece decelerates to stop.
Note that the operation restarts at STOP command OFF.
• Even if the current address overflows, no error occurs.
• The current address may overflow during unlimited length feed operation.
No error occurs even if the current address overflows, but note that the current address changes "from the
maximum value to the minimum value" or "from the minimum value to the maximum value."
2. Operation speed
The actual operation speed is "operation speed 1 x override setting."
3. Rotation Direction
The operation direction is decided by the sign of operation speed 1.
+: Operates in the direction which increases the current value.(Decelerates to stop when the value is 0.)
-: Operates in the direction which decreases the current value.
If the sign of the operation speed value changes, the reverse operation starts after decelerating to stop.
Caution
An abrupt change in the rotation direction may cause damage to the machine.
It may also cause an error through motor overload.
To change the rotation direction, set operation speed 1 value to 0, and wait for the motor to stop completely
after decelerating to stop.
If operation speed 1 value changes from positive to negative (e.g. 100 → -100), the work piece decelerates to
stop, and the 20SSC-H starts the reverse operation immediately.
