7-7 Option Functions (Group P)
For the functions available when using the optional PG Board (Model: 3G3AX-PG01), refer to 6-2
Sensorless Vector Control on page 6-4 to 6-9 Torque Control on page 6-56.
Select whether to have the inverter trip or continue operation with the error from the option unit ignored,
if an option error occurs.
• This function provides compensation for suppressing the variation of the rotation speed due to
temperature changes in the motor when Sensorless vector control, 0-Hz sensorless vector control, or
Sensor vector control is selected as the control method.
• Use the thermistor PB-41E (from SHIBAURA ELECTRONICS).
• To use this function, set the Thermistor Selection (b098) to 02 (NTC). Other thermistor settings do
not provide correct temperature detection.
• Use this function when using a communications unit to communicate with optional equipment.
• For details of parameters, refer to the following manuals.
• EtherCAT Communication Unit User’s Manual (I574)
• CompoNet Communications Unit User
’s Manual (I582)
• DeviceNet Communications Unit User
’s Manual (I581)
• Set the network slave address in the DeviceNet MAC ID (P192) or CompoNet Node Address (P190).
• In the Assembly Instance Number (P046), set the remote I/O function of the communications unit.
• If you select the flexible format for the remote I/O function, use the following parameters to configure
the interface for the remote I/O function.
• Option I/F Flexible Format Output Register 1 to 10 (P160 to P169)
• Option I/F Flexible Format Input Register 1 to 10 (P170 to P179)
• To command the inverter frequency reference as a rotation speed, set the number of motor poles in
the Number of Poles for Rotation Speed Setting (P049).
• In the Communications Error Detection Timer Setting (P044), set the function for monitoring the data
communications between the inverter and the communications unit.
• In the Operation Selection at Host Communications Error (P045), set how the inverter should operate
if an error etc. occurs in the host network.
