4. PARAMETERS FOR POSITIONING CONTROL
4 − 19
(3) External emergency stop signal (applies only when using MR-J2S-B/MR-J2-B)
The external emergency stop signal (EMG) can be made invalid.
0: External emergency stop signal is valid.
1: External emergency stop signal is invalid (automatically turned ON internally).
Since the emergency stop signal at the MR-J2-B cannot be used, do not set "0".
4.3.15 Optional function 2 (no-motor operation selection)
(1) Selection of no-motor operation (applies when using MR-H-BN only)
0: Invalid
1: Valid
If no-motor operation is selected, the output signals that would be output if the motor
were actually running can be output, and statuses indicated, without connecting the
motor.
This makes it possible to check the sequence program of the sequencer CPU
without connecting a motor.
(2) Electromagnetic brake interlock output timing (applies only when using MR-H-
BN)
Select the output timing for the electromagnetic brake interlock signal from
among the following.
0: Regardless of the rotational speed of the servo motor, output occurs under
any of the following conditions.
• Servo OFF
• Occurrence of an alarm
• Emergency stop input OFF (valid)
1: Output occurs under any of the above conditions provided that the servo
motor rotational speed is zero (expansion parameters).
(3) Selection of microvibration suppression function (applies to MR-J2S-B/MR-J2-
B)
Set to suppress vibration specific to the servo system on stopping.
0: Microvibration suppression control is invalidated
1: Microvibration suppression control is valid
(4) Motor lock operation (applies only when using MR-J2S-B/MR-J2-B)
Allows test operation with the motor connected but without rotating the motor.
The operation is the same as no-motor operation with MR-H-BN.
0: Motor lock operation is invalidated
1: Motor lock operation is valid
When motor lock operation is made valid, operation is possible without connecting
the motor. However, since when MR-J2S-B/MR-J2-B is used the connected motor
is automatically identified before operation is started, if no motor is connected the
connected motor type may be regarded as a default, depending on the type of
amplifier. If this default motor type differs from the setting made in the system
settings, the controller will detect minor error 900 (motor type in system settings
differs from actually mounted motor), but this will not interfere with operation.
