This will return the output mode (BFM #0), the offset data (BFM #10 to #13) and the gain data (BFM #14 to
#17) will be to the factory default status state.
1. Conditions
The sequence program described in this section is under the following conditions.
1) System configuration

3. Cautions regarding initializing
• During initialization, output is stopped, and H0000 is automatically written in the output status (BFM #6).
At the completion of initialization, the output status (BFM #6) will automatically change to H1111, and the
output will be restarted.
• It takes approximately 5 seconds to complete initialization. Do not set (write) data in the buffer memory
during the period.
• Priority is given to the setting of the change prohibition mode (BFM #19).
• Once initialization is completed, the value in BFM #20 will automatically change to "K0".
