DISABLE Serial communication function is disabled.
W / TIMER Enables serial communications with a watchdog timer. If there is no
serial activity (read or write) for more than 10 seconds, serial
control will turn off and the drive will stop.
W / O TIMR Enables serial communications without a watchdog timer. However,
after 10 seconds of no serial activity, serial control can be turned off
by issuing a STOP command from any source (keypad, terminal
strip) other than the serial link.
NOTE 1: The keypad STOP button and remote STOP input (TB-1) are always active,
regardless of what method (LOCAL, REMOTE, or SERIAL) is being used to control the
drive.
NOTE 2: If a RESET command (Parameter 65 - PROGRAM) is issued through the serial
link, this parameter will not default back to DISABLE. However, explicitly setting this
parameter to DISABLE through the serial link will cut off communication with the drive.
If developing an application for serial communications, refer to the RS-232/RS-485
Modbus or Metasys Communications Protocol Specification.
58 ADDRESS (SERIAL ADDRESS)
This parameter is used with the serial communications feature, and is intended for use in a
multiple drive network (RS-485). The serial link will support drives with addresses from 1
up to 255 (Metasysâ) or 247 (Modbusâ). If the serial communications option is not being
used, leave this parameter set to the default setting of 30.
61 PASSWORD (PASSWORD NUMBER)
This feature limits access to the programmable parameters for added security. The correct
password must be entered in order to change the parameters.
Pressing the PROG/RUN button on the keypad will activate the PASSWORD prompt. If the
correct password is entered, the PROGRAM MODE is entered and parameters can be
changed.
If the wrong password is entered, the display will flash ERROR: INCORRECT and then
return to the PASSWORD prompt to allow another attempt at entering the correct password.
