4. OPERATION AND FUNCTIONS
4.4.4 Test operation
Test operation can be performed by combining the Servo Configuration software that runs on the personal
computer and the servo amplifier.
This servo amplifier cannot use motor-less operation.
For details on the test operation, refer to the MR-J3- B Servo Amplifier Instruction Manual.
Function Item Usability Remarks
Jog operation Usable
Performed by the feedback of the motor encoder.
It is irrelevant to the load side encoder.
Positioning
operation
Usable
Program operation Usable
In the setting of parameter No.PA01, the operations can be set in the motor
encoder unit resolution unit or the load side encoder resolution unit.
In the setting of parameter No.PE01, semi closed loop control/fully closed
loop control can be set.
However, the semi closed loop control is always set only if parameter
No.PE01 is set to "
1".
For details, refer to section 4.1.2.
Output signal (DO)
forced output
Usable Same as the MR-J3- B servo amplifier function.
Test operation
Motor-less operation Unusable Not supported.
4.5 Absolute position detection system under fully closed loop system
POINT
When using a rotary encoder, the absolute position system cannot be
configured.
An Absolute type linear encoder is necessary to configure an absolute position detection system under fully
closed loop control using a linear encoder.
In this case, the encoder battery (MR-J3BAT) need not be installed to the servo amplifier.
Make setting to make Absolute position detection valid in the servo parameter (Parameter No.PA03). The
system can be used in the following limited conditions.
(1) Using conditions
1) Use an absolute type linear encoder with the load side encoder.
2) Select Always fully closed loop (Parameter No.PA01 1 , Parameter No.PE01 0).
(2) Absolute position detection range using encoder
Encoder type Absolute position detection enabled range
Linear encoder
(Serial Interface) Movable distance range of scale
(within 32-bit absolute position data)
(3) Alarm detection
The absolute position-related alarm (25) and warnings (92, 9F) are not detected.
