mech brake pick2
[12]
(Mechanical Brake Pick) Auxiliary contacts from mechanical brake switch 2. Asserted when
brake is picked (lifted).
nc ctct cfirm
[13]
(Normally Closed Contact Confirm) Opening of the auxiliary contacts confirming closure of
the motor contactor.
no function
[14]
(No Function) Input not assigned. When this setting is selected for one of the TB1 input
terminals, any logic input connected to that terminal will have no effect on drive operation.
NTSD Input 1
[15]
NTSD input #1 for use when the NTSD MODE is set to "1 Threshold", "2 Thresholds" or "3
Thresholds".
NTSD Input 2
[16]
NTSD input #2 for use when the NTSD MODE is set to "2 Thresholds" or "3 Thresholds".
ospd test src
[17]
(Overspeed Test Source) This function works only if the OVRSPEED TEST SRC switch is
set to EXTERNAL TB1. A true signal on this input applies the OVERSPEED MULT to the
speed command for the next run. After the run command has dropped, the drive returns to
‘normal’ mode and must be re-configured to perform the overspeed function again. The
OVERSPEED FLT level is also increased by the OVERSPEED MULT, allowing the elevator
to overspeed without tripping out on an overspeed fault.
NOTE: This input must be taken false then true each time that an overspeed test is run. If
the input is left in the true, it is ignored after the first overspeed test.
pre-trq latch
[18]
(Pre-Torque Latch) Transition from false to true latches pre torque command.
quick stop
[19]
(Quick Stop) This functions works when quick stop input becomes true, the drive will ramp
to zero speed quickly using the deceleration curve of DECEL RATE 3, DECEL JERK IN 3,
and DECEL JERK OUT 3 settings. Once the rising edge of QUICK STOP EN occurs, the
drive will force a zero speed reference and hold zero speed until either the removal of the
run command or removal of the drive enable.
rec travel en
[20]
(Recommended Travel Enable) When this input is given, the drive will automatically select
travel direction to ensure the lowest current draw from the mains supply based on feedback
from the encoder as the mechanical brake is lifting (usually used with a UPS as a means to
rescue trapped passengers where mains power is not available).
