Chapter 14. Output Signal Timing Charts
The start/stop signals (digital input 0) in the timing charts all assume that the value set for [P00: Start/stop
signal switching] is “1” (default value).
When the value set for [P00: Start/stop signal switching] is “0”, the ON and OFF statuses of the start/stop
signal (digital input 0) are inverted.
14.1 Timing Chart at Powering Up
The timing chart at powering up differs depending on the type of power supply as shown below.
 When sharing control power supply:
• Judge the charging completed/not completed status based on the alarm output or DOUT (READY
output).
• An alarm output before charging or after stopping indicates an abnormal status.
 Common power supply source to control and main circuit
