12.1-11-8
(not the motor’s rated current). The minimum value between Pr.11-17–11-20 and Pr.06-12
becomes the current output limit. In acceleration and steady state operation, when the output
current reaches the limit, the ocA (over-current during acceleration) protection or over-current
stall prevention under steady-state operation acts. The output frequency drops, and recovers
when the output current is lower than the limit value.
Refer to Pr.11-34 for calculation equation for the motor rated torque.
In IM: VF, VFDPG, SVC / PM, PMSVC modes, their 100% base values are the drive's rated
current, but for other control modes, 100% base values are the motor's rated current.
If Pr.00-11 = 8 (SynRM sensorless), then the default becomes 200.
11-21
Flux Weakening Curve for Motor 1 Gain Value
11-22
Flux Weakening Curve for Motor 2 Gain Value
Default: 90
Settings 0–200%
Adjust the output voltage for the flux-weakening curve.
For the spindle application, use this adjustment method:
1. Run the motor to the highest frequency.
2. Observe the output voltage.
