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.
Operation Selection on Option Error
Select whether to have the inverter trip or continue operation with the error from the option unit ignored,
if an option error occurs.
Parameter No.

P002
Secondary Resistance Compensation Function (Temperature Compensation)
• 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.
Parameter No.
P025
Communications Option Function
• 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
• DeviceNet Communications Unit User
• 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.
