Trips/Faults - Toshiba vlp technology P9 ASD Installation & Operation Manual

Trips/Faults

A Trip is an P9 ASD response to a Fault (though Fault and Trip are sometimes used interchangeably). A
Trip is a safety feature that disables the ASD system in the event that a subsystem of the ASD is
malfunctioning or a parameter setting has been exceeded.
Listed in Table 15

• Loss of suction pressure or closed pump output valve.
• Activated discrete input terminal set to Low Suction/No Flow Protection.
• ASD
• Emergency Off command received via EOI or remotely.
• Improperly positioned Sink/Source jumper on the Terminal board or on an
option device (see J100 at the Terminal PCB of the ASD).
• Sink/Source configuration is incorrect.
• F630
• Braking sequence discrete input and output terminals are not set up properly.
• ASD is configured to receive a signal from a shaft-mounted encoder and no
signal is being received while running.
• Disconnection at the Encoder circuit.
• Motor is stopped and is generating torque via torque limit control.
• ASD is not configured properly.
• Result of a motor speed that is greater than the commanded speed when
using an encoder for speed control.
• Improper encoder connection or setup information.
• Defective encoder.
• Same key input for 20 seconds or more.
• V/I signal loss.
• Terminal Board failure.
• P24 over-current condition.
• F633
• CPU data Transmit/Receive error.
• Torque processing error.
• Make service call.
• Software processed incorrectly.
• Make service call.
• Incorrect voltage applied to the discrete input terminals.
