Decimal 27 29 25 17 m n1 n2
[Defined Area] 1 ≤ m ≤ 2 49 ≤ m ≤ 50
0 ≤ n1 ≤ 255
0 ≤ n2 ≤ 255
[Initial Value] n1 = 0, n2 = 0
[Function] Set external buzzer drive pulse condition.
m specifies the buzzer drive terminal that sets the condition.
m Buzzer Drive Terminals
1, 49 Buzzer drive terminal 1
2, 50 Buzzer drive terminal 2
n1 specifies the energizing time; n2 specifies the delay time.
• Energizing time = 20 msec x n1
• Delay time = 20 msec x n2
The drive of the external buzzer set by this command is performed by m n1 n2.
The set value is not initialized by “@”, or .
