The setting of power supply perdurabgility is further described below.
In the present embodiment, power perdurabgility setting based on report lock actuation time.It can will complete needed for reporting lock
Actuation time value be power delay time of failure detection, band-type brake pull up time and brake response time
The sum of three.It should be noted however that the present inventor has found after further investigation, calculate in the manner described above
To actuation time can not accurately portray complete band-type brake needed for the time.In order to more accurately estimate actuation time, should will bear
Load factor is taken into account.Such as it can be by the actuation time being calculated in the manner described above multiplied by a coefficient greater than 1.Allusion quotation
Type, the delay time for failure detection of powering is 10ms, and relay actuation time 20ms, the brake response time is 30ms,
It thus can be 2 × (10+20+30)=120ms (being herein 2 by coefficient value) by actuation time such as value needed for report lock.
By taking the α i servo amplifier used in FANUC series NC system as an example, itself it can be tieed up after servo amplifier power-off
The power-on time held is about 50ms.It therefore only can not the actuation time needed for completing to report lock by servo amplifier itself after powering off
Interior maintenance power supply, that is to say, that the backup power supply of such as ups power etc is essential.Therefore master control after power-off
Device power supply processed needs to maintain at least power supply of 120ms, and during this period, supply voltage must not be lower than the 90% of normal voltage.It is elected
When selecting the Siemens Sitop series 24v regulated power supply with buffer module, since the three phase supply of the power supply is from main open circuit
After device, therefore either external power supply disconnects either closing main circuit breaker, can all cut off the power supply of the power supply.At this point, working as
It is 100ms that load current, which is the power supply buffer time of 40 ampere-hours, is 200ms when load current is 20 ampere-hours, when fully loaded negative
Load electric current is 30 ampere-hours, may thereby determine that power supply buffer time is 150ms, that is, master controller power supply can also be tieed up after powering off
Hold 150ms.In this case, the confession of master controller can be maintained during completing holding brake action being not connected to ups power
