5.4 Replacement of MR-J2- B by MR-J2S- B
When using the MR-J2S- B on the servo system controller peripheral software incompatible with the
MR-J2S- B, you cannot use some parameter functions. Read this section carefully and set appropriate
values in the parameters.
5.4.1 Main modifications made to the parameters
The following table lists the parameters whose settings have been modified from the MR-J2- B or added
to the MR-J2S- B. The peripheral software of the servo system controller may not be compatible with
some parameters whose settings are different or have been added. For details, refer to the servo system
controller manual.
Parameter
No.
Code Name Main modifications/additions
(Note) Setting from peripheral
software of conventional servo
system controller
6 FBP Feedback pulse number The encoder resolution of the
compatible motor changed to 131072
pulses/rev. Setting cannot be made.
The resolution is 16384
pulses/rev.
8 ATU Auto tuning Gain adjustment modes were
increased. Setting can be made but the
added modes cannot be used.
9 RSP Servo response level The response level setting range
was increased to meet the enhanced
response. Some response levels cannot be
set.
18 NCH Machine resonance suppression
filter 1
(Notch filter) The machine resonance suppression
filter (notch filter) setting range was
increased. Some filter frequencies cannot
be set.
20 INP In-position range The setting unit become the
feedback pulse unit in parameter
No. 6. Setting can be made.
22 MOD Analog monitor output The data that may be output by
analog monitor was added. Setting can be made but the bus
voltage cannot be set.
25 LPF Low-pass filter/adaptive
vibration suppression control The low-pass filter and adaptive
vibration suppression control
functions were newly added. Setting can be made.
31 ERZ Error excessive alarm level The setting unit was changed in
response to the enhanced resolution
(131072 pulses/rev) of the encoder. Setting can be made but the
setting unit is [0.1 rev].
33 OP6 Optional function 6 The communication baud rate with
the personal computer was changed
to max. 57600bps. Setting cannot be made.
38 ENR Encoder pulses output The encoder feedback pulses can be
output from the servo amplifier.
These pulses can be set. Setting cannot be made.
