Standard Settings for Servo Drives Using MECHATROLINK Section 6-4
Note The PCU uses the forward drive prohibited input, reverse drive prohibited
input, and origin return deceleration limit switch allocated in the Servo Drive’s
external inputs as the forward rotation
limit input signal, reverse rotation limit
input signal, and origin proximity input signal, respectively. Make sure that
these input signals maintain a signal width no shorter than the MECHA-
TROLINK communications cycle. If the input signal width is shorter than the
communications cycle, the PCU is unable to detect the input signals, and
operations cannot be performed normally.
6-4-4 SMARTSTEP Junior Servo Drive Settings (R7D-ZN @ -ML2 with
Built-in MECHATROLINK-II Communications)
When the R7D-ZN @ -ML2 SMARTSTEP Junior Servo Drive Settings equipped
with built-in MECHATROLINK-II communications is used, the Servo Drive’s
default settings are used as the standard settings for MECHATROLINK com-
munications.
Compulsory Parameter
Settings The following Servo parameter must be set to enable PCU control. Do not
change this setting.
Pn800.1 Communications Control: Warning Check Mask
The MECHATROLINK communications warnings A.94 (parameter setting
warning) and A.95 (MECHATROLINK command warning) are used when the
PCU is controlling communications. Set the parameter so that they are not
ignored. Either leave Pn800.1 set to the default setting 4 (ignores communica-
tions errors (A.96) only) or set to 0 (detects A.94, A.95, and A.96).
Standard Settings for I/O
Signals When Using
MECHATROLINK When the R7D-ZN @ -ML2 SMARTSTEP Junior Servo Drive equipped with
built-in MECHATROLINK-II communications is used, the Servo Drive's default
settings are the standard settings for I/O signals for MECHATROLINK com-
munications. The standard I/O signal settings are used for limit inputs, origin
searches, interrupt feeding, and other position control functions of the Position
Control Unit. Use the default settings for the I/O signal allocations for the
Servo Drive.
