Direct Access Parameter Information
Q9 Plus ASD Install/Op Manual
PTC 2 Thermal Selection
Program Special Special Parameters
This parameter Enables/Disables the optional external thermal
detection circuit of the Expansion IO Card Option 2. A thermistor
is connected from TH1+ to TH1- of TB4 on the Expansion IO
Card Option 2.
Should the thermistor resistance reading fall below 50W because
of an over-temperature condition or exceed 3000W because of
an open circuit, an External Thermal Fault (OH2) will be incurred.
Note: While this parameter is Enabled, the system cannot be
restarted until the thermistor value recovers to the level of
1.8 k
from an over-temperature condition. An Auto-
Restart will not be initiated subsequent to an External
Thermal Trip (OH2). A manual restart will be required in the
event of an OH2 trip.
Settings:
0 — Disabled
1 — Detect Disconnect
Direct Access Number —
F638
Parameter Type — Selection List
Factory Default — Disabled
Changeable During Run — No
Braking Resistance Overload Time (not used)
Program Protection Dynamic Braking
This parameter sets the time that the braking resistor is allowed
to sustain an overload condition before a trip is incurred.
This feature is useful for applications that have a fluctuating load
or for loads that require a long deceleration time.
