Unit Description / Notes
If P202  3 (V/F, VVW or Vector with Encoder control), the comparison
of N > Nx to activate the brake will always use the Real Speed, regardless
of the selection ("31 = Brake (Ref)" or "30 = Brake (Vel))".
NOTE!
Refer to figures 6.39 q), r) and s).
Preliminary settings:
Nx (P288) = 7 % to 10 % of the motor speed (Sensorless Control), 2 %
to 5 % of the speed (Vector with Encoder Control)
Ix (P290) = 20 % to 130 % of P401
P355 = 0 seconds
P354 = 1.5 x time to activate the brake
P356 = 0.85 x time to release the brake
P353 = 0.2 seconds
NOTE!
These preliminary settings are suggestive and may be changed
according to the application.
- Overweight - Situation where the lifted load weight is greater than the
maximum allowed.
When the CFW-09 is powered up, the output set to the option "32 =
Overweight" is activated. In order to deactivate the output, i.e., detect
the overweight condition, the following conditions shall be satisfied:
- P361 = 1 (Load Detection = On);
- Parameters P362, P363 and P367 properly set;
- P367 (Overweight Level) lower than the output current (P367 < Is)
during the stabilization time.
If P361 = 0 (Load Detection = Off) – the output always remains
activated.
- Slack Cable - Situation where the lifted load weight is lower than the
minimum weight detected by the crane.
When the CFW-09 is powered up, the output set to the option "33 =
Slack Cable" is activated. In order to deactivate the output, i.e., detect
the slack cable condition, the following conditions shall be satisfied:
- P361 = 1 (Load Detection = On);
- Parameters P362, P363, P364 and P365 properly set;
- Slack cable condition detected.
