AE & AEK Series Communication Protocol

5-2 Output current setting
To multiply the setting current of 100 and convert the value into hex code,
please write High byte first followed by Low byte on the addresses of
0x73, 0x72.
Ex: To set O/P current setting to 45.75A, please multiply 45.75 by 100, then convert 4575 into
Hex code. Write hex code of 0x11DF, 0x11, 0xDF into the address of 0x73, 0x72.
After current setting, the current stores in the buffer of SMPS. Please refer to the
explanations of 5-3, to renew the O/P current.
5-3 Setting parameter update
After setting Voltage and Current stores in buffer, the setting parameters will not be
updated immediately. The setting parameters will present after checking procedure of
writing 1 on the bit2 of Control Register [0x7C] is complete, and bit 2 will become 0. After
bit 2 become 0, please do the following:
1)The setting will be denied when the setting value is over limits. The O/P will remain
unchanged and the bit3 of control Register (0x7C) commands will show 1 as error.
2)The setting will be effective when the setting value is set within its limits. The O/P
setting will be updated, the bit3 of control Register [0x7C] commands will show 0
as valid.
5-4 Power on/off control (In Remote mode [0x7C.7]=1 only)
To Power off, write “0” into the bit0 of control Register [0x7C]
To Power on, write “1” into the bit0 of control Register [0x7C]
5-5 Remote / Local control
Write “0” on bit7 of control Register [0x7C] to enter Local mode. Setting
of voltage, current and On/Off control will be controlled by VCI, ACI and ENB signal.
Write “1” on bit7 of control Register [0x7C] to enter Remote mode. Setting
of voltage, current and On/Off control will be controlled by I
2
C bus.
5-6 Others
User must only write “0”
