Special Parameters
PTC2 Thermal Selection
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 50
because of an over-
temperature condition or exceed 3000
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.

Braking Resistance Overload Time (10x rated torque)
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.
