Yaskawa GPD503 Drive - Manual (Page 106)

4.3 PRE-OPERATION CONSIDERATIONS
• After completing the start-up, connect the motor to the load.
• Additional control circuit wiring can be added, and constants in the GPD 503 can be
programmed to configure the drive system to your specific application, including “Remote”
(2-wire or 3-wire) Control. (See Table 2-1 for listing of Programmable Features
descriptions.)
4.4 STORAGE FUNCTION
The GPD 503 uses internal NV-RAM to store information when power is removed or in the
event of a power failure. Therefore, when power is reapplied, operation will begin at the
same state as when power was removed.
The following information is stored:
1. Last monitor display selection (in Drive mode).
2. Last frequency command setting and forward/reverse selection from Digital
Operator.
3. The sequence of failure conditions that occurred before power was removed
(including content of CPF failure).
