(4) Feedback position
The motor rotational quantity is indicated in unit q’ty after pulse correction. If pulse correction is not used, the motor encoder rotation q’ty
itself will be indicated.
(In case of 16 bit serial encoder, 65536 pulses per rotation)
Remarks : If the rotating direction has been altered by system para. 80, an increase from the current position raises the reading.
The maximum positive count of 99,999,999 is followed by 0. The maximum negative count of -99,999,999 is followed by 0.
I.e., the count becomes 0 every
±
100,000,000. The indication is correct even when rotated by the load (mechanical system).
4 digits preceded by "H" are high order 4 digits, and those by "L" are low order 4 digits.
In case of a negative value, H (or L) and - (minus sign) appears alternately.
(5) Command position
The position of motor controlled by the amplifier is displayed in unit quantity after pulse correction.
If, after a target position is attained, the run command has been turned off and if the motor is rotated by the load (mechanical system), a
correct position is not displayed.
(6) Deviation amount
Displays the difference between command position and feedback position. The deviation is displayed in terms of encoder pulse count.
Pressing the MODE key holding down the SHIFT key
interchanges the high order 4 digits and low order 4
digits.
Pressing the MODE key holding down the SHIFT key
interchanges the high order 4 digits and low order 4
digits.
Pressing the MODE key holding down the SHIFT key
interchanges the high order 4 digits and low order 4
digits.
