Drive Address
This parameter is used to set the address when controlling the drive cont roll er by a Modbus device via
the RS-485 port. The baud rate is selectable as 9600 or 19,200 bits/sec .The r a nge o f addre sses i s 0 t o
31. The factory setting is 0, indicating that the drive c ontroller is not being controlled v ia 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.
Assignable I/O Functions
The table below shows the possible I/O assi gnments f or the ATV58 TRX Type H driv e controller and the
optional I/O Extension Cards. Only one I/O extension card or one commu nicati on card can be i nstal led
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 . conta ct and 1 N .C . cont act) and cannot be
re-assigned.

[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.
