192 H9 ASD Installation and Operation Manual

PTC2 Thermal Selection

Program ⇒ Special ⇒ Special Param eters ⇒ PTC2 Thermal Selection
This parameter Enables/Disables the optional external thermal detect ion 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 Ext ernal
Thermal Fault (OH2) will be incurred.
Note: While this parameter is Enabled, the system cannot be restarted
until the thermistor value recov ers 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:

Braking Resistance Overload Time (10x rated torque)

Program ⇒ Protection ⇒ Dynamic Braking
This parameter sets th e time that the braki ng resistor is allowed t o sustain and
overload condition before a trip is incurred.
This feature is useful for application s that have a fluctuating load or for loads
that require a long deceleration time.
