Setting
Bits 0 to B Reserved
Bit C: Reset Network
0: OFF, 1: ON
Turn ON this bit to reset the entire
MECHATROLINK network.
Bit D: Drive Permission
0: OFF, 1: ON
Enables (ON) or disables (OFF) the Inverter drive
control.
• This bit is captured at both rising and falling
edges.
• When set to 0 (OFF), the command Inverter Drive
Control cannot be used.
• When this bit turns ON from OFF, the request to
prepare for inverter control operation is sent.
However, this request will not be accepted while
the command Inverter Drive Control is being exe-
cuted. To allow the Inverter to get ready to run,
turn OFF this bit and then turn it ON again after
setting a command other than Inverter Drive Con-
trol.
• When this bit turns OFF from ON while the com-
mand Inverter Drive Control is being executed, bit
3 (Command Error Completed Status) of the
monitoring parameter Command Status will turn
ON. Also, when this bit turns OFF from ON while
the Inverter is operating, the system will execute
Forced OFF (OFF both for forward RUN and
reverse RUN).
Bit E: Communication
Reset
0: OFF, 1: ON
Re-establishes the connection for MECHATROLINK
communications with the Inverter, whether commu-
nications are stopped or in process. Also clears the
Alarm monitor parameter.
• This bit is captured at the rising edge.
<Application Example>
With the setting to continue communications after a
communications error occurrence,* the SVC Func-
tion Module will continue communications whether
or not the Inverter stops communications because
of the error. In this case, the connection for com-
munications can be re-established by executing the
Communications Reset command. By resetting
communications, you can re-establish communica-
tions with the Inverter.
Bit F: Alarm Clear
0: OFF, 1: ON
Clears the Alarm monitor parameter.
• This bit is captured at the rising edge.
• If communications are stopped after the MECHA-
TROLINK communication errors, clear the alarm
bit and re-establish communications by setting
this bit to 1 (ON).
Note: Alarm Clear is used to clear alarms in the
SVC Function Module, but will not clear
alarms and warnings in the Inverter. To
clear alarms in the Inverter, use the Inverter
Drive Control command and set the bit 9
(Fault Reset) of Input Command
(OW10) to 1 (ON).
