Operation Sequence; Power On Sequence - Sanyo SUPER BL P5 Manual

6. OPERATION
6.1

Operation Sequence

The frequency of power ON/OFF should be 10 times/H or less, and 50 times/day or less.
6.1.1

Power ON Sequence

Control power ON (r, t)
Sequence power ON (CN1)
Amplifier ready output (RDY)
Start ready ON (external switch)
Main circuit power supply
Dynamic brake release
Start ready complete (SRDY)
1 The time period from main circuit power ON to SRDY is approx. 1 sec. However, in
case of single phase power of Amplifier with 50A capacity, that will be approx. 1.5 sec.
Install a spark killer
on the magnetic contactor
