Description
Parameter 5
Fetches general-purpose contact
information and stores it in <variable>. (0 =
off, 1 = on)
Fetches general-purpose contact
information and stores it as word data in
<variable>.
Outputs bit data to a general-purpose
contact. (0 = off, 1 = on)
Outputs word data to a general-purpose
contact.
Operates an inverter input terminal. (0 = off,
1 = on)
Fetches information from an inverter output
terminal.
Fetches information from an inverter input
terminal.
Turns on the terminal specified by <variable
1> after the time specified by
<variable2/constant> elapses.
Turns off the terminal specified by <variable
1> after the time specified by
<variable2/constant> elapses.
Sets <variable/constant> in a specified
timer and starts the timer.
Stops the specified timer.
Fetches internal user contact information
and stores it in <variable>. (0 = off, 1 = on)
Fetches internal user contact information
and stores it as word data in <variable>.
Outputs bit data to an internal user contact.
(0 = off, 1 = on)
Outputs word data to an internal user
contact.
Replaces the content of <display code>
with <variable/constant>.
Reads the content of <display code> into
<variable>.
Stores a data of only one parameter
changed by chg param command that is
issued immediately after the execution of
eeprwrt command to EEPROM. (SJ700/
L700/ SJ700B series doesn't correspond.)
The clock data is substituted for six bytes
that make <variable> a head. Moreover,
the clock data is regularly updated. (Only
WJ200 Step2 corresponds.)
The clock data is substituted for six bytes
that make <variable> a head. Moreover,
the update of the clock data is stopped.
(Only WJ200 Step2 corresponds.)
The inverter decelerate and stop the motor
Displays <variable> on user monitor (ii)
Displays the result of operation with
<variable1> and <variable2> on user
monitor (ii)
Value of user monitor (ii) is read out to
<variable>
Makes the inverter trip
