Inverter does not switch off (see parameter P931).
3‘Active low’ = relay OPEN. ‘Active high’ = relay CLOSED.
This operates in the same manner as the external brake control (described in P063/P064), except that the relay is not activated.
0 = Normal stop mode
1 - 3 = Do not use
4 = Combination stop mode
Only effective if the relay output is set to control an external brake (P061 = 4). In this case when the inverter is switched on, it will run at the minimum frequency for the time set by this parameter before releasing the brake control relay and ramping up (see illustration in P064).
As P063, only effective if the relay output is set to control an external brake. This defines the period for which the inverter continues to run at the minimum frequency after ramping down and while the external brake is applied.

Notes: (1) Settings for P063 and P064 should be slightly longer
|
|
|
|
|
| than the actual time taken for the external brake to |
|
|
|
|
|
| apply and release respectively. |
|
|
|
|
|
| (2) Setting P063 or P064 to too high a value, especially |
|
|
|
|
|
| with P012 set to a high value, can cause an |
|
|
|
|
|
| overcurrent warning or trip as the inverter attempts to |
|
|
|
|
|
| move a locked motor shaft. |
P065 |
| Current threshold for relay (A) | 0 - 99.9 |
| This parameter is used when P061 = 9. The relay switches on when | |
|
|
| [1.0] |
| the motor current is greater than the value of P065 and switches off | |
|
|
|
|
|
| when the current falls to 90% of the value of P065 (hysteresis). |
