Starting Modes
Soft Start
This mode has the most general application. The motor is given an
initial torque set ting, which is user-adjusta ble from 0 to 90% of
locked rotor torq ue. Fro m the init ial torque l e v el, t he output v olt age t o
the motor is steplessly inc rea sed during the acceleration ramp time.
The acceleration ramp time is user-adjustable from 0 to 30 seconds. If
the SMC Dialog Plus controller senses that the motor has reached the
up-to-speed condition during the voltage ramp operation, the output
voltage automatically switches to full voltage.

Energy Saver
Phase Rebalance
The Energy Saver feature is typically use d in app lications where the
motor is lightly loaded or unloaded for extended periods of time.
With the Energy Saver f eature enabled, the SMC Dialog Plus
controller continuously monitors motor load with its interna l
feedback circuit ry. Because SCRs control the output voltage, motor
power losses may be redu ced by decreasing the motor terminal
voltage.
Notes: (1) The Energy Saver feature is not available when a bypass
contactor is used.
(2) When Energy Saver and Phase Rebalance are both
enabled, Phase Rebalance takes precedence in operation.
Wit h the Phase Rebalance feature enabled, the SMC Dialog Plus
controller continuously monitors the incoming three-pha se line
voltage and automatically adjusts the output voltage to balance the
three phase currents dr awn by the motor.
Notes: (1) Phase Rebalance requir es that the Bulletin 825 conv erter
module is utilized.
(2) Phase Rebalance is not active during byp ass ope r ation.
(3) When Phase Rebalance and Energy Saver are both
enabled, Phase Rebalance takes precedence in operati on.
Protection and
Diagnostics
The SMC Dialog Plus controller provides the protective and
diagnostic features described below.
Overload
The SMC Dialog Plus controller meets applicable requirements as a
motor overload protective device. T hermal memory provides added
protection and is maintained even when control po wer is removed . The
built-in o verload algorithm controls the value stored in P aramet er 11,
Motor Thermal Usage; an Overload Fault will occur when this value
reaches 100%. The programming parameters below provide
application flexibility and easy setup.

inhibit the controller’ s current measure ment capability .
To compensate for additional motor heating that may

Protection and Diagnostics
(cont.)
Notes: (1) The factory default setting for Overload Class, which is
“Off,” disables overload protection. An overload trip
class and the motor’s full load current rating must be
programmed to enable overload protection.
(2) The current sensing capability of the SMC Dialog Plus
controller is disable d during bypass operation. Using a
Bulletin 825 converter module in these appli cations is
recommended to provi de curre nt feedback. Otherwise, a
separate overload relay is required.
(3) Motors with full load current ratings of 5 Amps and
below may requir e the use of the converter module
(Cat. No. 825-MCM20) for improved current
measurement accuracy.
(4) Automatic reset of an overload fault requires the start
input to be cycled in a 2-wire contr ol scheme. This
applies to the follo wing firmware relea ses: 1.07
(standard), 1A07L (Soft Stop) and 1B05L (Pump
Control) or earlier.

Metering
Excessive Starts/Hour
The SMC Dialog Plus controller allows the user to program the
allowed number of starts per hour (up to 99). This helps eliminate
motor stress caused by repeated starting over a short time period.
Overtemperature
The SMC Dialog Plus controller monitors the temperature of the
SCRs by using interna l thermistors. When the po wer poles’ maxi mum
rated temperature is reache d, S CR firing is inhibited.
An overtemper ature condition can indicate inadequate ventilation,
high ambie nt temper at ure, over l o a d in g, or exc essive cy cling. After
the SCR temperature is reduced to allowable levels, the fault c an be
cleared (see page 9-1 for instructions).
Power monitoring parameters include:
•Three-phase curren t
•Three-phase v oltage
•Power in kW
•Power usage in kWH
•Power factor
•Motor thermal capacity usage
•Elapsed time
Notes: (1) The current sensing capability of the SMC Dialog Plus
controller is disable d during bypass operation. A
Bulletin 825 converter module is required to maintain t he
three-phase current, kW, kWH, and motor thermal
capacity measurements.
(2) Current measurement is not available during the slow
speed and/or braking operations of the Preset Slow
Speed, SMB Smart Motor Braking, Accu-Stop and Slow
Speed with Braking control opti ons.
(3) Voltage measurement is not available during the braking
operation of the SMB Smart Motor Braking, Accu-St op,
and Slow Speed with Braking control options.
(4) The power fac tor parameter is pro vide d as a displacement
power fa ctor value. Powe r factor measurement is
disabled during bypass operation.
(5) The elapsed time and kWH values are automatically
saved to memory every 12 hours.
(6) Motor thermal capacity usage is deter mined by the built-
in electronic thermal overload protection system. An
overload fault occurs when this value reaches 100%.

Ventilated Enclosures
For Type 1 (IP42) enclosures, the following guidelines are
recommended to limit the maximum controller ambient temperature.
There should be a clearance of at least six inc hes (15 cm) above and
below the contr oller. This area allows air to fl ow thro ugh the
heatsink. Ventilation openings are required above and below this air
space.
The ventilation outlet should be placed at least six inches (15 cm)
above the con troller with the ventilation inlet placed near the bottom
of the enclosure. A filter is required to preve nt contaminants from
entering the enclosu re.
Use the table below to det erm ine the minimum ventilation openings
and fan/blower requirements.
Cutout size is the same as required for the particular fan or blower being used.
