4.3 Set point
The set point screen can be used to change set point
values. Use the numerical keypad displayed to select set
points and press OK to confirm the new set point.
Factory and user settings are stored in the motor control
system. The settings are preserved in the memory even
if the mains voltage is switched off or if the hand-held
terminal is removed.
4.4 Modbus communication
The hand-held terminal communicates with the motor
control system via Modbus RTU, with the following
Modbus settings:
• Autodetect = Autoscanning to find the address, must
be set to On.
• Address = Modbus address.
• Baud rate = 38.4
• Parity = None.
• Stop bits = 1/2.
The motor control system has two Modbus settings, one
preset and one alternative.
Preset Modbus setting:
• Address = 54.
• Baud rate = 38.4
• Parity = Even.
• Stop bits = 2.
Alternative Modbus setting. Set at the from the factory:
• Address = 0.
• Baud rate = 115.2 kbps.
• Parity = Even.
• Stop bits = 2.
It is possible to change the alternative Modbus setting
with the help of a Modbus register.
The motor control system automatically detects whether
communications occur via the preset or alternative
Modbus setting. If no communications occur via the
preset Modbus setting after 10 seconds the motor control
system searches for the alternative Modbus setting and
vice versa.
4.5 Change Modbus address
Wait 10 seconds so that settings can be saved before the
hand-held terminal is switched off.
The motor control system will search for the preset
Modbus setting for 10 seconds before searching for the
alternative Modbus setting.
4.6 Shock-absorbing casing
The hand-held terminal is equipped with a silicone casing
that protects against shocks, oils and dirt.
