Altivar® 58 TRX AC Drives

Configurable I/O Functions

Drive Address

This parameter is used to set the address when controlling the drive controller by a Modbus device via the RS-485 port. The baud rate is selectable as 9600 or 19,200 bits/sec.The range of addresses is 0 to 31. The factory setting is 0, indicating that the drive controller is not being controlled via the RS-485 port.

Reset Counters

This parameter can be used to reset the watt-hour meter or the run time meter back to zero.

CONFIGURABLE I/O FUNCTIONS

Configurable I/O Functions can be viewed and modified only when the access locking switch on the keypad display is in the total unlock position (see page 24). These parameters can be modified only when the motor is stopped.

Default I/O Configurations

Selecting a macro-configuration automatically assigns the inputs and outputs to functions suitable for the application. The table below shows the drive controller I/O assignment as a function of the macro- configuration selected.

[1]Factory default setting for 100 hp products and below.

[2]If the Freewheel Stop/Run Permissive function is configured, the drive controller will not start the motor unless the logic input is connected to +24 V.

[3]For 125–500 hp controllers, the factory settings are:

LI3 = fault reset; LI4 = Not assigned; AI1 = Reference summing; AI2 = Reference summing; R2 = Drive running.

Assignable I/O Functions

The table below shows the possible I/O assignments for the ATV58 TRX Type H drive controller and the optional I/O Extension Cards. Only one I/O extension card or one communication card can be installed in the drive.

The following I/O are on the drive controller.

Logic Input 1 (LI1) is configured for Run Forward when the drive controller is set for two wire control and configured for STOP when the drive controller is set for three wire control.

Relay Output 1 (R1) is configured as a fault relay (1 N.O. contact and 1 N.C. contact) and cannot be re-assigned.
