(26)Peak current detection setting (Un\G300)
Set whether to enable or disable the peak current detection for each channel.
For details on the peak current detection function, refer to the following.
Peak Current Detection Function (
b15 b14 b13 b12 b11 b10 b9 b8 b7 b6 b5

b8 to b15 are fixed to "0".
(a) Enabling the setting
Turn on then off Operating condition setting request (Y9) to enable the setting.
(b) Default value
All channels are set to Disable (1).
(27)Peak current detection flag (Un\G301)
The peak current status can be checked with this flag for each channel.
For details on the peak current detection function, refer to the following.

(a) Peak current detection flag (Un\G301) status
• When CH Digital output value (Un\G11 to Un\G18) exceeds set CH Peak current detection value
(Un\G326 to Un\G333) consecutively for the duration of CH Peak current detection time (Un\G318 to
Un\G325) set in advance, Peak current detected (1) is stored in Peak current detection flag (Un\G301) of
the corresponding channel.
• When a peak current is detected in even one of the channels for which the digital conversion or peak
current detection are enabled, Peak current detection signal (X7) turns on.
(b) Clearing Peak current detection flag (Un\G301)
To clear Peak current detection flag (Un\G301), turn on then off Error clear request (YF) when the digital output
value is the peak current detection value or less.
Peak current detection flag (Un\G301) is also cleared by turning on then off Operating condition setting request
(Y9).
