Yaskawa GPD503 Drive - Manual (Page 141)

SECTION C. ALL GPD 503 s (CONTINUED)
Control Braking Torque Approximately 20%
Characteristics
(continued)
V/F Pattern Selection 15 Standard Patterns:
4 for general purpose; 4 for high starting torque;
4 for fans and pumps; 3 for machine tools.
1 custom pattern: defined by control constant settings.
Motor Overload Protection Electronic thermal overload relay
Instantaneous Overcurrent Motor coasts to a stop at approximately 200% rated current.
Fuse Blown Protection Motor coasts to a stop by blown fuse.
Overload Motor coasts a stop after 60 sec. overload condition.
Overvoltage Motor coasts to a stop if GPD 503 DC bus voltage exceeds
400 V (230V unit), 800V (460V unit), 1040V (575V unit).
Protective Undervoltage Motor coasts to a stop if GPD 503 DC bus voltage drops to
Functions 210 V or below (230V unit), 420V or below (460V unit),
546V or below (575V unit).
Momentary Power Failure Factory setting provides for motor to coast to a stop after
momentary power failure of more than 15 ms. Can be
reprogrammed to allow continuous operation (ride-through)
during power failure of up to 2 seconds (see Note 4).
Heatsink Overheat Thermostat
Stall Prevention Stall prevention at acceleration /deceleration and constant
speed operation.
Ground Fault Provided by electronic circuit.
Power Charge Indication "CHARGE" lamp remains lit until bus voltage drops below 50 V.
Location Indoor (protected from corrosive gases and dust).
Ambient Temperature -10 to 40oC (+14 to 104°F)
Environmental
Conditions
Storage Temperature (Note 5) -20 to 60oC (-4 to 140°F)
Humidity 90% RH (no condensation)
Vibration 1 G at less than 20 Hz, up to 0.2 G at 20 to 50 Hz.
SECTION B. ALL GPD 503 s (Continued)
NOTES:
1. Overload capacity: 150% of rated for 60 sec.
2. Overload capacity: 125% of rated for 60 sec.
3. Overload capacity: 115% of rated for 60 sec.
4. For a 230/460 V GPD 503 less than 5HP, ride-through function up to 2 second momentary power failure requires
connection of an external capacitor unit between external main circuit terminals B1/+ and –.
5. Temperature during shipping. Storing in this temperature for a long period may deteriorate main circuit capacitor.
