Rtcset On, Rtcset Off - Hitachi NT2021XA Instruction Manual

rtcset on, rtcset off

- Format
rtcset on <variable>
rtcset off <variable>
- Explanation
This instruction is a function in the WJ200 Series.
The clock data of six bytes sent from WOP is stored in six bytes that make
"year", "month", "date", "day of the week", "hour" and "minute".
In the rtcset on instruction, the clock data is regularly updated after the clock data is substituted.
In the rtcset off instruction, the update of the clock data by rtcset on instruction is stopped after the clock data is substituted.
The data stored in "rtcset on / off U (00)" are as follows.
Example) Monday, April 19, 2010 11:15
U (00) = 1004h = 4100
U (01) = 1901h = 6401
U (02) = 1115h = 4373
Moreover, it is as follows when a variable is set to UL (00).
UL (00) = 10041901h = 268704001
UL (01) = 11150000h = 286588928
Note : It is necessary to connect WOP with the inverter to acquire the clock data. When WOP is not connected, all
clock data is set to 0.
- Sample program : Program to make the inverter operate the motor for forward rotation for 1 hour

Description
a head. Clock data is 1 byte for each in
: Clock data is stored in U (02) to U (04).
: Add to the present time for 1 hour.
: When it will be data more than in 24:00,
it pulls for 24 hours.
: Clock data is stored in U (05) to U (07).
: Start forward rotation of the motor.
: Stop the update of the clock data.
: Decelerate and stop the motor.
