PTC2 Thermal Selection

Program Special  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.
Settings:
0 — Disabled
1 — Detect Disconnect

Braking Resistance Overload Time (10x rated torque)

Program Protection Dynamic Braking
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.

Step-Out Current Detection Level

Program Motor PM Motor
This parameter is used with synchronous motor applications only.
