On a machine controlled by the winMulti software using 300Hz Elte spindles, it is critical that the deceleration times in winMulti and on board the drive are the same. On a recent visit to Nationwide, the Shrack relays were blackened, indicating a arcing situation on the contacts. This can only happen if the inverter is still active when the relay contacts are switched off. Unfortunately, it is very easy for a machine to unwittingly be in this state. | On a machine controlled by the winMulti software using 300Hz Elte spindles, it is critical that the deceleration times in winMulti and on board the drive are the same.

There may be a valid reason why the drive parameter F08 has been increased to, say 0.5. If this is the case, increase the psInvDecel300Hz to 500 to match it. The bigger this decel time is, the slower the machine cycle time will be, but the most important outcome is that the winMulti parameter is greater than or equal to the inverter parameter. </translate> | There may be a valid reason why the drive parameter F08 has been increased to, say 0.5.

Details
On a machine controlled by the winMulti software using 300Hz Elte spindles, it is critical that the deceleration times in winMulti and on board the drive are the same. On a recent visit to Nationwide, the Shrack relays were blackened, indicating a arcing situation on the contacts. This can only happen if the inverter is still active when the relay contacts are switched off. Unfortunately, it is very easy for a machine to unwittingly be in this state.
Correct setup
To ensure the relay switches off AFTER the inverter has finished its deceleration cycle, the deceleration time in the winMulti parameters must be equal to or longer than the deceleration parameter in the drive. (Note that one is in milliseconds, another is in seconds)
Factory defaults:
| Drive Parameter Jaguar VSM | F08 | 0.4 (in seconds) |
| Drive Parameter Yaskawa | C1-02, C1-06 | 0.4 |
| winMulti Parameter | psInvDecel300Hz | 400 (in milliseconds) |
| Drive Parameter Jaguar VSM | F08 | 0.2 (in seconds) |
| Drive Parameter Yaskawa | C1- |
There may be a valid reason why the drive parameter F08 has been increased to, say 0.5. If this is the case, increase the psInvDecel300Hz to 500 to match it. The bigger this decel time is, the slower the machine cycle time will be, but the most important outcome is that the winMulti parameter is greater than or equal to the inverter parameter.
