4. OPERATION AND FUNCTIONS
[Explanation of display items and functions]
For the monitor display item, click "Start monitor" to read it continuously from the amplifier. Click
"Stop monitor" to stop read.
For the parameter item, click "Read parameter" to read it from the amplifier, and click "Write
parameter" to write.
Name
Explanation
Command pulse
frequency
Commands from the host controller are counted and displayed.
Click "Clear" to reset the value to 0.
Cumulative feedback
pulse
Feedback pulses from the servo motor encoder are counted and displayed.
Click "Clear" to reset the value to 0.
Droop pulses
When the full closed function is "invalid", a deviation from the command that uses the servo
motor encoder as F/B is displayed.
When the full closed function is "valid" or "semi/full switching", a deviation from the
command that uses the closed encoder as F/B is displayed.
Cumulative feedback
pulse 2
Feedback pulses from the full closed encoder are counted and displayed.
The value is displayed in the pulse unit of the closed encoder.
Click "Clear" to reset the value to 0.
Encoder data
The data of the closed end encoder are displayed.
The displayed data change depending on the closed encoder type.
ID
: The ID number of the encoder is displayed.
Data 1 : In the case of the INC type, a counter starting at power-on is displayed.
In the ABS type linear encoder, absolute position data is displayed.
In the case of the ABS type rotary encoder, a multi-revolution counter is
displayed.
Data 2 : In the case of the INC type, the distance (number of pulses) from the reference
mark (Z phase) is displayed.
In the ABS type linear encoder, 00000000 is displayed.
In the case of the ABS type rotary encoder, a cycle counter is displayed.
Polarity
A or sign is displayed according to the full closed encoder polarity specified in the full
closed selection parameter.
Note: Full closed encoder polarity
is displayed when the setting is "0: Address increasing direction for motor CCW".
Z-phase pass state
When the full closed function is "invalid", the Z-phase pass state of the servo motor encoder
is displayed.
When the full closed function is "valid" or "semi/full switching", the Z-phase pass state of
the closed encoder is displayed.
Full closed switching
device
Displayed only when "semi/full switching" is selected for the full closed function.
The switching device selection command state and the internal state during selection are
displayed.
Parameter
The parameter related to the full closed control is displayed.
Its setting can be changed and the new value can be written to the servo amplifier.
The related parameters are as follows.
Electronic gear
: Pr. 6
Dual F/B filter
: Pr. 67
FCM
: Pr. 65
FCD
: Pr. 66
Full closed selection
: Pr. 62, 63, 64
