MN715P General Information 2-2

WARNING: Do not use motor overload relays with an automatic reset feature.

These are dangerous since the process may injure someone if a
sudden or unexpected automatic restart occurs. If manual reset
relays are not available, disable the automatic restart feature using
external control wiring.

WARNING: This unit has an automatic power up start feature that will start the

motor whenever input power is applied and a RUN (FWD or REV)
command is issued and maintained. If an automatic power up start
of the motor could cause injury to personnel, this feature should be
turned off.

WARNING: Be sure the system is properly grounded before applying power. Do

not apply AC power before you ensure that grounds are connected.
Electrical shock can cause serious or fatal injury.

WARNING: Do not remove cover for at least five (5) minutes after AC power is

disconnected to allow capacitors to discharge. Electrical shock can
cause serious or fatal injury.

WARNING: Motor circuit may have high voltage present whenever AC power is

applied, even when motor is not rotating. Electrical shock can
cause serious or fatal injury.

WARNING: Dynamic brake resistors may generate enough heat to ignite

combustible materials. Keep all combustible materials and
flammable vapors away from brake resistors.

Caution: Suitable for use an a circuit capable of delivering not more

than 5,000 RMS symmetrical amperes, at rated voltage.

Caution: Disconnect motor leads (T1, T2 and T3) from control before

you perform a “Megger” test on the motor. Failure to
disconnect motor from the control will result in extensive
damage to the control. The control is tested at the factory for
high voltage / leakage resistance as part of Underwriters
Laboratories Inc. requirements.

Caution: Do not connect AC power to the Motor terminals T1, T2 and

T3. Connecting AC power to these terminals may result in
damage to the control.

Caution: Baldor recommends not using “Grounded Leg Delta”

Section 3
Receiving and Installation

3-1 Receiving and Installation MN715P

Receiving & Inspection

The Series 15P Inverter control is thoroughly tested at the factory and
carefully packaged for shipment. When you receive your control, there are
several things you should do immediately.

1. Observe the condition of the shipping container and report any damage
immediately to the commercial carrier that delivered your control.

2. Verify that the control you received is the same as listed on your
purchase order.

3. If the control is to be stored for several weeks before use, be sure that it
is stored in a location that conforms to published storage specifications.
(Refer to Section 6 of this manual).

Physical Installation

The mounting location is important. The control should be installed in an area
that is protected from direct sunlight, corrosives, harmful gases or liquids,
dust, metallic particles and vibration. Exposure to these elements can reduce
the operating life and degrade performance of the control.

Several other factors should be carefully evaluated when selecting a location
for installation:

1. For effective cooling and maintenance, the control should be mounted
on a smooth, non-flammable vertical surface. Table 3-1 lists the Watts
Loss ratings for enclosure sizing.

2. Provide at least two inches of clearance on all sides for airflow.

3. Front access must be provided to allow the control cover to be opened
or removed for service and to allow viewing of the Keypad LEDs.

4. Altitude derating. Up to 3300 feet (1000 meters), no derating is
required. Above 3300 feet, derate peak or continuous output current by
2% for each 1000 feet above 3300 feet.

5. Temperature derating. Up to 40°C, no derating is required. Above
40°C, derate peak or continuous output current by 2% per °C above
40°C.
Maximum ambient is 55°C.

Control Installation

The control must be securely fastened to the mounting surface. Use the four
(4) mounting holes to fasten the control to the mounting surface or enclosure.

Shock Mounting

If the control will be subjected to levels of shock greater than 1G or vibration
greater than 0.5G at 10 to 60Hz, the control should be shock mounted.
Excessive vibration within the control can cause internal connections to
loosen and could lead to component failure or electrical shock hazard.

MN715P Receiving and Installation 3-2

Electrical Installation

Interconnection wiring is required between the motor control, AC power
source, motor, host control and any operator interface stations. Use UL listed
closed loop connectors that are of an appropriate size for the wire gauge
being used. Connectors are to be installed using crimp tool specified by the
manufacturer of the connector. Only Class 1 wiring should be used.

System Grounding

Baldor controls are designed to be powered from standard three phase lines
that are electrically symmetrical with respect to ground. System grounding is
an important step in the overall installation to prevent problems.

AC Line Connections

A power disconnect should be installed between the input power service and
the control for a fail-safe method to disconnect power. The control will remain
in a powered-up condition until all input power is removed from the control and
the internal bus voltage is discharged.

Protective Devices

Recommended fuse sizes are based on the following:

115% of maximum continuous current for time delay.
150% of maximum continuous current for Fast or Very Fast action.

Note: These general size recommendations do not consider harmonic currents or

ambient temperatures greater than 40°C.

Be sure a suitable input power protection device is installed. Use the
recommended fuses listed in Tables 3-4 and 3-5 (Wire Size and Protection
Devices). Input and output wire size is based on the use of copper conductor
wire rated at 75 °C. The table is specified for NEMA B motors.

Line Reactors

3 phase line reactors are available from Baldor. The size of the line reactor to
use is based on the maximum continuous load. If providing your own line
reactor, use the following formula to calculate the minimum inductance
required. Table 3-2 lists the input current required for this calculation. Line
reactors may be used at the control output to the motor. When used this way,
they are called Load Reactors.

Motor Brake Connections

For motors with spring set brakes, connect the brake power leads and the
motor power leads separately. Because the inverter has variable voltage
output to the motor, the inverter may not supply enough power at low
frequencies for proper brake operation. If using a motor with an internally
connected brake, the brake power leads must be connected to a separate
power source for proper brake operation. Refer to Figure 3-2 for terminal
locations.

Optional Dynamic Brake Hardware

Dynamic Brake (DB) Hardware must be installed on a flat, non-flammable,
vertical surface to obtain effective cooling and operation. The ambient
temperature must not exceed 80°C. DB connections are shown in Figure 3-6.

Troubleshooting

5-1 Troubleshooting MN715P

The Baldor Series 15P Control requires very little maintenance, if any, and
should provide years of trouble free operation when installed and applied
correctly. Occasional visual inspection to ensure tight wiring connections and
cleaning to remove dust, dirt, or foreign debris which can reduce heat
dissipation should be considered.

Operational failures called faults are displayed on the LED’s as they occur.
Procedures in this section describe how to recognize a fault and restore
normal operation.

Before service is performed, all input power must be removed from the control
to avoid electrical shock hazard. Most troubleshooting can be performed
using only a digital voltmeter having an input impedance exceeding 1
megohm. In some cases, an oscilloscope with 5 MHz minimum bandwidth
may be useful. Before consulting the factory, check that all power and control
wiring is correct and installed per the recommendations given in this manual.

Fault Code Determination

When the Fault LED is blinking, a failure has been detected. One of five fault
codes is displayed by the flashing Fault LED. To determine the fault code,
carefully observe the blinking pattern. The blinking (2Hz rate) should stop for

1.5 seconds. This 1.5 second pause is the start of the display sequence.
Count the number of blinks that occur between the 1.5 second pauses. One
blink = Fault code 1, two blinks = fault code 2 etc. When the fault code is
determined, refer to Fault Code Descriptions.

Fault Code Descriptions

Five fault codes can be displayed. Carefully examine all LED’s (Power, Fault,
FWD, REV and Stop) to determine the cause of the fault condition. Press
Stop to reset the control.
