Fieldbus

Use the Fieldbus screen to configure communication settings when using Modbus RTU or MODTCP/EIP communications.

On each screen you can load the current settings by clicking Read All Parameters.

Parameter data can be adjusted by selecting the appropriate radio button or drop-down menu item. To update multiple parameters, click Write All Parameters to copy the parameter values to the servo. To update just the parameters bounded by the blue box, click Write Selected Item(s)

Modbus RTU

Use this screen to configure communication settings for Modbus RTU.

SureServo2 - Modbus RTU

Option	Function
Station Number Setting	P3.000 sets the address for the drive when using RS-485 communications. This is an absolute address for the drive on the communication network and must be unique. The default value is 0x7F, possible settings are 0x01 to 0x7F. This is a normal requirement for serial networks. If using an Ethernet network (see below), this value must also be set for proper communication.
Communication Protocol	P3.002 sets the communication protocol to use used. Use the drop down menu to select from the 9 available options. The default setting is 6: 8,N,2 (MODBUS RTU).
Communication Timeout	P3.004 sets the communication timeout in seconds. If the value is 0, no timeouts will occur, otherwise a timeout will occur after the selected number of seconds. The default value is 0, possible settings are 0 to 20 seconds.
Transmission Speed Setting	P3.001 configures the transmission speed to be used for communications on each port using a hex setting. The default value is 0x0203, possible settings are 0x0000 to 0x3405. Each digit after the x configures a different port:   U Z Y X Communication Port - - - RS-485 Range 0 0-2 0 0-5 The numerical value entered for range represents the following: 0=4800 1=9600 2=19200 3=38400 4=57600 5=115200 Note that the communication speed of USB is set at 1.0 Mbit/s and cannot be changed.
Communication Error Handling	P3.003 sets how the system will respond to communication errors. If set to 0 (first radio button) the system will display a warning but the motor will continue to operate. If set to 1 (2nd radio button) the system will display a warning and the motor will decelerate to a stop. If deceleration is chose, you can also configure the deceleration time in ms using P5.003.B. Select your desired value from the drop down.

MODTCP / EIP

Use this screen to configure communication settings for MODTCP/EIP.

SureServo2 - Modbus RTU

SureServo2 - EIP - Implicit

SureServo2 - EIP - Explicit

Option	Function
NOTE: Although Station Number Setting (P3.000 from the RTU screen) is typically not required for Ethernet communications, the SureServo2 drive requires that this value is set. If P3.000 is not set correctly, Ethernet communications may not work.
IP Configuration	P3.049 determines whether the system will use Static (0) or DHCP controlled (1) IP addressing. If you select 0, you need to manually configure the IP address using P3.050 through P3.061.
IP Address	P3.050, P3.051, P3.052, P3.053 are used to configure the first, second, third, and fourth octets of the IP address. The system default is 192.168.1.10, but you can use any valid IP address.
Net Mask	P3.054, P3.055, P3.056, P3.067 are used to configure the first, second, third, and fourth octets of the net mask. The system default is 255.255.255.0, but you can use any valid net mask.
Gateway	P3.058, P3.059, P3.060, P3.061 are used to configure the first, second, third, and fourth octets of the gateway address. The default is 0.0.0.0, but you should configure to match your gateway address.
Reset to Factory Defaults	P3.064 resets the system to factory defaults. Press this button to return all addressing to the factory setting.
Push Parameters to Card	P3.065 writes the configured settings to the communication card.
Communication Card Error Status	P3.048 displays any communication errors with the comm card. By default, this box should be empty. Possible error codes include: Error Code Display Description 0 N/A No error 75 ECFF Incorrect factory parameters default setting. 80 ECEF Ethernet connection error. 81 ECto Communication timeout. 83 ECrF Reset communication card to default setting. 86 ECiP IP address setting error 89 ECcb Communication card cannot communication with SureServo2.
Ethernet Timeout Duration of Communication Card	P3.067 sets the Ethernet timeout detection in ms. Default value is 30ms, possible settings are 1 to 600 ms.
Ethernet Timeout Detection of Servo Drive	P3.068 enables or disables the timeout function for EtherNet communications. 1 enables timeouts, while 0 disables them.
Ethernet Timeout Handle of Servo Drive	P3.069 configures the system response to an Ethernet timeout. Default is 1, possible settings are 0 to 4. For the ramp to stop option, P5.003.C will set the deceleration slope, but cannot be configured on this screen.
Write Timeout Settings	Press this button to write the values of P3.067, P3.068, and P3.069 to the communication card.
