5.2 Description of Statuses
Table 5.2 Status
Data
Position
Number
Status Description
*81/*82 Target Position
Status [pulses]
Reads the operation target position during a positioning operation.
The operation target position is determined from the Target Position Mode and
Target Position, set at the beginning of the positioning. The Operation Target
Position always contains absolute position data, regardless of whether the
Target Position Mode is absolute or relative.
*83/*84 Current Position
Status [pulses]
This represents the current position of a motor as output pulse counts of the
positioning module. It is thus not the actual motor position when a servomotor is
used.
*85/*86 Current Speed
Status
[(1/65536)
pulses/ms]
Reads the current speed of a motor as output pulse counts of the positioning
module. It is thus not the actual speed of the motor when a servomotor is used.
Regardless of the direction of the motor’s rotation, the value is zero or positive.
*87 Contact Input Status
Reads the state of the external contact inputs and the encoder Z-phase input.
The state of each contact is stored as 1 bit (0: off; 1: on). If a contact is specified
as an “a” contact, it is represented by “1” when the contact input circuit is closed.
If a contact is specified as a “b” contact, it is represented by “1” when the contact
input circuit is open.
bit 0: negative-direction limit input
bit 1: positive-direction limit input
bit 2: origin input
bit 3: encoder Z-phase input
*88 Error Status
Reads the error code when an error occurs. It has no meaning if the Error
Notification input relay is off. For details, refer to Section 8.2, “Error Codes.”
*89 Alarm Status
Reads the alarm code when an alarm occurs. A value of ‘0’ indicates no alarm.
There is no separate alarm notification input relay. For details, refer to Section
8.3, “Alarm Codes.”
*90 Origin Search Status Reads the status during or at the end of an origin search.
0: On power-up or at normal end of the origin search
1: Stopped upon detection of an input edge of “Stop immediately” or “Decelerate
and Stop”.
2: Stopped by a “Stop immediately” or “Decelerate and Stop” command.
3: Stopped by an error
4: During a Z-phase search
5: Before a Z-phase search
*91 Extended Status Reads the state of an axis during positioning or jog stepping as bit data. When
an axis is in a particular stage of motion, the corresponding bit is ‘1’.
bit 0: Accelerating (at the time of operation start)
bit 1: Moving at constant speed
bit 2: Decelerating (during a Decelerate & Stop operation)
bit 3: Accelerating or decelerating (during a Change Speed operation)
bit 4: During a Change Target Position operation
*92/*93 Number of Flash
Memory Write
Operations
Reads the total number of flash memory write operations that has been
performed. As there is a limit to the number of times data can be saved in the
flash memory (100,000 times maximum), save the entry parameters to the flash
memory only when required. The performance of the flash memory is not
assured after 100,000 writes.
The symbol
‘*’
designates the value of (axis number - 1). The values for axis 1 to axis 8 are 0 to 7 respectively.
