5.2 RJ45 Communication Connection
The RJ45 Data Port can be used as either a RS485 Serial Modbus interface or to connect the optional remote keypad
(VS1ST-RKEY3) and/or copycat loader (VS1ST-CCL).
Serial Modbus networks use the RS485 PIN connection; see Appendix E for the communication protocols. Remote
keypad kits and copycat programmers use the dedicated MXSTbus connection.

3 0V
4 RS485 - / MXSTbus
5 RS485 + / MXSTbus
6 +24V Keypad
7 RS485 - / Modbus
8 RS485 + / Modbus
For MXSTbus and Modbus,
data format is fixed as:
1 start bit, 8 data bits,
1 stop bit, no parity.

5.3 Changing Parameters
To change a parameter value press and hold the ENT/PROG key for > 1 second while the drive displays
. The
display changes to
indicating parameter 01. Press and release the ENT/PROG key to display the value of this
parameter.
Use the UP and DOWN arrow keys to change to the required value. Press and release the ENT/PROG key
once more to store the change. Press and hold the ENT/PROG key for > 1 second to return to operational mode.
The display shows
if the drive is stopped or the real-time information (for example speed) if the drive is running.
5.4 Reset Factory Default Settings
To reset factory default parameters, press the UP, DOWN, and STOP keys simultaneously for > 2
seconds. The display shows
indicating the drive has reset itself to factory default parameters. Press the STOP
button to acknowledge and reset the drive.
5.5 Terminal Control
When delivered, the VS1MX is set to operate in terminal control mode and all parameters (P-xx) have the default values as
indicated in Chapter 7 Parameters. Connect the motor to the drive, checking star/delta connection for the voltage rating.
1. Remove all power from the control.
2. Connect a control switch between the control terminals 1 and 2 ensuring that the contact is open (drive disabled).
3. Connect a potentiometer (1 kΩ min to 10 kΩ max) between terminals 5 and 7, and the wiper to terminal 6.
4. With the potentiometer set to zero, switch on the power supply to the drive. The display will show
.
5. Enter motor data from motor nameplate:
P-01 = motor rated voltage
P-02 = motor rated current
P-03 = motor rated frequency
P-04 = motor rated speed
