DRIVE SETUP AND ADJUSTMENT
60
elevator speed. Effective only when logic
input A1TB1-10 is active. Selecting this ramp
rate will override Rates 1 or 2.
Function #179
Decel #3 Time
Units: SEC
Range: 0.50 – 15.00
Default 5.00
Total deceleration time in seconds for S-curve
ramp #3 from rated speed to zero speed.
Effective only when logic input A1TB1-10 is
active. Selecting this ramp rate will override
Rates 1 or 2.
Function #180
Accel #3 %S
Units: %
Range: 0.1 – 100.0
Default: 25.0
The percent of time that will be spent in the
controlled jerk or S-portion of the timed ramp
curve during ramped acceleration #3. A
percent S of 0.1% corresponds to almost all
linear acceleration. A percent S of 100% will
make the S-curve #3 smooth with no linear
acceleration portion.
Function #181
Decel #3 %S
Units: %
Range: 0.1 – 100.0
Default: 25.0
The percent of time that will be spent in the
controlled jerk or S-portion of the timed ramp
curve during ramped deceleration #3. A
percent S of 0.1% corresponds to almost all
linear deceleration. A percent S of 100% will
make the S-curve #1 smooth with no linear
deceleration portion.
Function #182
Invert Alarm Relay
Units: logic
Range: 0 (Off) – 1 (On)
Default: 0 (OFF)
Alarms are classified as non-critical faults
detected by the DSD 412 that pose no
immediate need to stop operation. The Alarm
output relay K2 (on the Drive Control PCB,
A1) is reserved for non-critical fault
indications. It has a normally open contact
wired to A1TB1-38 and 39). With function 182
set to 0 (OFF), the default, relay K2 will pick-
up, closing the contact on the occurrence of a
non-critical fault. With function 182 set to a 1
(ON), the relay will be picked-up during
normal operating conditions and drop out on
the occurrence of a non-critical fault or Alarm.
Alarms are presently identified as drive over-
temperature or thermistor failure, motor or
transformer thermostat over-temperature, and
motor overload trip. Other conditions may be
selectable to be alarms or critical faults.
