Cn-28: Stall Prevention Level During Factory setting:

Acceleration (Constant Torque Region)

Range: 30 to 200 %

Cn-29: Stall Prevention Limit During Factory setting:

Acceleration (Constant HP Region)

Range: 30 to 200 %

The stall prevention during acceleration extends the acceleration rate according to the

load status with respect to the level programmed into Cn-28 or Cn-29 (based on GPD 503

rated current; see Table A3-1) and protects the motor from stalling during acceleration.

Cn-30: Stall Prevention Level During Operation Factory setting:

160

at Set Frequency

Range: 30 to 200 %

During operation while the speed is constant, if the GPD 503 output current exceeds the

stall prevention level set into Cn-30, the output frequency is reduced to a level to prevent

motor stalling. If the output current returns to a value lower than Cn-30, the output

frequency returns to its previous level.
