• If Actual Speed (J40) is > Velocity Threshold 1 (H13) then Velocity Threshold 1 Status Output (J48) = Off (0).
This threshold may be used as an at speed indication where Velocity Threshold 1 Status Output (J48) is routed to the elevator controller via a digital
output, such that when the speed is below a certain level, the elevator controller can open the doors early.
In RFC-A and RFC-S the speed threshold is based on speed feedback, but in Open loop mode it is based upon the profile generator speed since
there is no feedback device available.
This sets the velocity threshold 1 switch threshold where:
RFC-A, RFC-S
If Actual Speed (J40) is <= Velocity Threshold 2 (H14) then Velocity Threshold 2 Status Output (J49) = On (1).
If Actual Speed (J40) is > Velocity Threshold 2 (H14) then Velocity Threshold 2 Status Output (J49) = Off (0).
This threshold may be used for advanced door opening where Velocity Threshold 2 Status Output (J49) is routed to the elevator controller via a digital
output, such that when the speed is below a certain level, the elevator controller can open the doors early.
In RFC-A and RFC-S the speed threshold is based on speed feedback, but in Open loop mode it is based upon the profile generator speed since
there is no feedback device available.
In closed loop, this sets the maximum speed error threshold in mm / s. The error is calculated from Profile Speed (J39) - Actual Speed (J40). Trip 62
(Speed err) is generated when the calculated error is > Maximum Speed Error Threshold (H15) for 1 s continuously.
If Maximum Speed Error Threshold (H15) = 0 then Trip 62 (Speed err) is disabled.
Maximum Speed Error (J57) shows the maximum speed error for the current travel. It is reset when a new travel begins.
This sets the maximum distance error threshold in mm. T
he er
ror is calculated from the integral of Profile Speed (J39) - Actual Speed (J40). Trip 63
(Distance err) is generated when the calculated error is > Maximum Distance Error Threshold (H16) for 1s continuously.
If Maximum Distance Error Threshold (H16) = Off (0) then Trip 63 (Distance err) is disabled.
Maximum Distance Error (J56) shows the maximum distance error for the current travel. It is reset when a new travel begins.
