• Soft starting and soft stopping of AC motors.
• Integrated electronic overload protection (Class 10)*.
• Serial communication (Modbus) over RS485**.
* RSGD VD210, VD210C, VX210, VX210C, VX310C, VX311C models only,
** RSGD VD210C, VX210C, VX310C, VX311C models only.
Three phase AC motor soft starter
Benets
• Easy to use. The RSGD is equipped with a self-
learning algorithm that automatically adjusts the
start parameters to optimise the motor starts and
stops.
• Fast installation and set-up. Only 3 settings are
required (FLC, ramp-up and ramp-down).
• Compact dimensions. 12 - 45 Arms in 45 mm wide
housing, 55 - 100 Arms in 75 mm wide housing.
• Integrated protection. Diagnostic functions
provide additional protection. RSGD is also
equipped with an overload protection (Class 10).*
• Torque control during ramp-down. Smoother
deceleration of the load.
• Complete monitoring. The RSGD is equipped
with a Modbus/RTU communication port by 2-wire
RS485 connection.**
• Guided model selection. Easy to use selection
tool to select the appropriate soft starter model
depending on the application type.
Description
RSGD is an extremely compact and easy to use
3-phase soft starter for AC induction motors rated
up to 100 Arms.
The starting parameters can be easily set-up
through 3 selector switches.
The integrated motor overload protection (Class
10)* and Modbus communication** result in a
higher installation exibility.
Applications
RSGD soft starters are the ideal solution for 3-phase xed speed AC induction motor applications where there
is the need to reduce the starting current and/or minimise stresses on the motor during start and stop.
The RSGD o󰀨ers a number of integrated diagnostic functions that can replace additional components inside
the electrical panel.
Typical applications include: compressors, pumps and fans.

Ramp-up Mode of operation
1 or 2 seconds
• When the ramp-up knob is in position 1 or 2, the RSGD will follow a self learning current
limit algorithm.
• As soon as A1-A2 (or ST for RSGD60 models) control voltage signal is applied, the RSGD
will start to ramp-up the motor.
• At the very rst start the current limit will be 4 x FLC setting.
• In the subsequent starts, the RSGD will automatically adjust the current limit setting to
maintain the motor start time as close as possible to the ramp-up time setting.
≥ 5 seconds
• When the ramp-up knob is in position 5 or above, the RSGD will follow a self-learning
current ramp algorithm.
• The RSGD will start with a set of default parameters for starting torque.
• Depending on the ramp-up time setting, the RSGD will apply a current ramp algorithm to
start the motor as close as possible to the set ramp-up time.
• During the motor start, the current will be limited to a maximum of 3.5 x FLC setting.
• In the subsequent starts, the RSGD will continue to adjust the starting parameters of initial
torque and current ramp to ensure that the motor is started as close as possible to the set
ramp-up time.
Ramp-down Mode of operation
1 to 30 seconds
• During ramp-down, the RSGD works on a torque control algorithm for smoother stopping
of the motor.
• As soon as the control voltage signal A1-A2 (or ST for RSGD 60 models) is removed, the
RSGD will slow down the motor gradually according to the ramp-down setting.
• The power semiconductors will be switched OFF as soon as the time (as per ramp-down
setting) has elapsed unless there is a risk of exceeding the maximum temperature on the
semiconductors. In such a case the RSGD will leave the motor to coast to stop.
0 seconds • If the ramp-down knob is set to 0, the RSGD will leave the motor to coast to stop (no ramp-
down).
The RSGD series of soft starters works on two distinct self-learning algorithms depending on the ramp-up time
settings.
