PTC2 Thermal Selection
No Path — Direct Access Only
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 50Ω because of an over-
temperature condition or exceed 3000Ω 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 1.8kΩ 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
Braking Resistance Overload Time (10x rated torque)
No Path — Direct Access Only
This parameter sets the time that the braking resistor is allowed to sustain and
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.
