Origin Compensation Value
The origin compensation value setting determines the amount of adjustment
that is applied when adjustment is necessary after the origin has been deter-
mined (e.g., if there is inaccuracy in the position at which the proximity sensor
turns ON or if the motor has been changed). After the origin is initially
detected using origin search, the number of pulses specified with this setting
are output, the present position is set to 0, and at the same time, the origin is
established (the No Origin Flag turns OFF).
Setting range: C0000001 to 3FFFFFFF Hex (–1,073,741,823 to
1,073,741,823)
The operation patterns that are determined by the above settings are illus-
trated on the following pages.
6-4-3 Operation Mode Settings
Mode 0 An open collector output signal such as a sensor is connected to the origin
input signal, and the origin input signal response time is 0.1 ms. (N.O. contact
setting)
In this mode, an origin input signal error (error code 6202) will be generated if
an origin input signal is input during the deceleration from origin search high
speed to origin search proximity speed which is initiated by the input of an ori-
gin proximity input signal (or a limit input signal if the origin detection method
is set to 3).
Mode 1 The Z-phase signal from the Servo Drive is connected to an origin input sig-
nal. An origin input signal is input and, within an interval of approximately
20 ms after the stop, a error counter reset signal is output.
In this mode, if an origin input signal is input during the deceleration from ori-
gin search high speed to origin search proximity speed which is initiated by
