8.User Mechanism Settings, Operation, and Commands
(8) AXMREV (rated rotation speed) · AXJMX (maximum rotation speed) · AXENCR (encoder
resolution)
These parameters set the properties of the servomotor, which can be used. Referring to the
specifications in "Instruction Manual for Servo Amplifier", set the values which are suitable for the
applied servomotor. The default value of AXMREV is 2000(r/min.), the default value of AXJMX is
3000(r/min.) and the default value of AXENCR is 8192 (pulse/rev).
[Example]
When the properties of the servomotor set "Control axis No. of servo" as the 1st axis are as follows.

AXMREV = 3000, 2000, 2000, 2000, 2000, 2000, 2000, 2000, 2000, 2000, 2000, 2000, 2000, 2000,
2000, 2000
(Set "3000" to the 1st element.)
AXJMX = 4000, 3000, 3000, 3000, 3000, 3000, 3000, 3000, 3000, 3000, 3000, 3000, 3000, 3000,
3000, 3000
(Set "4000" to the 1st element.)
AXENCR = 16384, 8192, 8192, 8192, 8192, 8192, 8192, 8192, 8192, 8192, 8192, 8192, 8192,
8192, 8192, 8192
(Set "16384" to the 1st element.)
When MELSERVO-J2-Super series is used as a servo amplifier, it is necessary to set the encoder
resolution in the basic parameter No. 6, "FBP," of the servo amplifier.
(9) AXJOGTS (JOG smoothening time constant)
Set this parameter to reduce the vibration if it occurs during jog of the additional axis. If any
excessive value is set, the acceleration/deceleration time becomes long during jog operation. The
settable value is in the range of positive real numbers. The default value is 150.00 (ms).
[Example]
When this parameter value is set to "200.00" against vibration of the axis set "Control axis No. of
servo" as the 1st axis,
AXJOGTS = 200.00, 150.00, 150.00, 150.00, 150.00, 150.00, 150.00, 150.00, 150.00, 150.00,
150.00, 150.00, 150.00, 150.00, 150.00, 150.00
(Set "200.00" to the 1st element.)
(10) MEJAR (joint operating range)
For this parameter, set the motion range of the additional axis in order of minimum value and
maximum value. To set the additional axis of multi-mechanisms, change all parameters excluding
the user designated origin (USERORG) parameters, and then turn the power from off to on. Next,
select a user mechanism to be used, and then set this parameter. The settable values are real
numbers in the range of -80000.00 to 80000.00. The default values are -80000.00, 80000.00.
[Example]
When it is used as the multi mechanism (number of mechanism axes: 1 axis), set the motion range
as follows.
Minimum value
Maximum value
MEJAR = –2000.00, 3000.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00
0.00, 0.00
(Set –2000.00 at the 1st element and 3000.00 at the 2nd element.)
