This equipment may be connected to other machines that have rotating parts or parts that are controlled by this equipment. Improper use can cause serious or fatal injury. Only qualified personnel should attempt the start-up procedure or troubleshoot this equipment.

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 f eature using external control wiring.

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

WARNING: This unit has an automatic restart feature that will start the motor whenever input

power is applied and a RUN (FWD or REV) command is issued. If an automatic restart of the motor could cause injury to personnel, the automatic restart feature of the VS1MSD should be disabled.

WARNING: Be sure the system is properly grounded before applying power. Do not apply AC

power before you ensure that all grounding instructions have been followed. 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. Dangerous voltages are present inside the equipment. Electrical shock can cause serious or fatal injury.

WARNING: Improper operation of control may cause violent motion of the motor shaft and driven

equipment. Be certain that unexpected motor shaft movement will not cause injury to personnel or damage to equipment. Certain failure modes of the control can produce peak torque of several times the rated motor torque.

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.

WARNING: The motor shaft will rotate during the touting procedure. Be certain that unexpected

motor shaft movement will not cause injury to personnel or damage to equipment.

CAUTION: Disconnect motor leads (U, V & W) 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 Underwriter Laboratory requirements.

CAUTION: Suitable for use on a circuit capable of delivering not more than the RMS

symmetrical short circuit amperes listed here at rated voltage.

Horsepower RMS Symmetrical Ampheres

1-30 5,000

CAUTION: Do not connect AC power to the Motor terminals U, V and W. Connecting AC power

to these terminals may result in damage to the control.

CAUTION: Baldor recommends not to use "Grounded Leg Delta" transformer power leads that

may create ground loops. Instead, we recommend using a four wire Wye.

CAUTION: Only Baldor cables should be used to connect the keypad and control. These are

special cables to protect the control and keypad. Damage associated with other cable types are not covered by the Baldor warranty.

CAUTION: If an M-Contactor is installed, the control must be disabled for at least 200msec

before the M-Contactor is opened. If the M-Contactor is opened while the control is supplying voltage and current to the motor, the control may be damaged. Before the control is enabled, the M-Contactor must be closed for at least 200msec.

CAUTION: Use of power correction capacitors on the output of the drive can result in erratic

operation of the motor, nuisance tripping, and/or permanent damage to the drive. Remove power correction capacitors before proceeding. Failure to observe this precaution could result in damage to, or destruction of, the equipment.

1.1 Change from Main Source to 2nd Source

The function of parameters P46 and P47 has been changed. A digital input can now select between the main control and speed setting selected in parameters P38 and P40 and the secondary source set in parameters P46 and P47. A digital input programmed in t1 to t8 must be set to “22” Exchange between second source and drive.

1.2 Parameters

P46 Drive Start/Stop Source 2

Range: 0 to 3 (see table for P38) Default: 0 = Keypad Access: Configurable See Also: P38, P47, t1 to t8

This parameter serves as an alternate control mode. It is selectable by a digital input (t1 to t8) = “22” Exchange between second source and drive.

P47 Frequency Setting Mode 2

Range: 1 to 7 (See table for P40) Default: 1 = Keypad Access: Configurable See Also: P40, P47, t1 to t8

This parameter serves as an alternate speed reference mode. It is selectable by a digital input (t1 to t8) = “22” Exchange between second source and drive.

NOTE: Parameters P46 and P47 are only viewable when one of the t1 to t8 terminals is set equal to “22”.

Errata Sheet for the VS1MD Drive Installation & Operating Manual

22 = Exchange between second source and drive: When the defined input is turned ON, the values set in drv2 and Frq2 are used for control and reference to the drive. Settings for drv2 and Frq2 can not be changed while the digital input is closed. During the change over from the Main Source to the 2nd source, the drive will stop if the control source differs. To restart the drive, a new run command must be given.

Digital/Relay Output On/Off Delay

A timer function has been implemented by adding four new software parameters. Two are for the On Delay and two for the Off Delay timer to the digital outputs of the VS1MD drive. Setting a value of greater than zero will begin the On, Off or both timers when the condition set in t32 and t33 for the digital outputs is met.

In the case of the On delay timer, the actual output will not change state until the time value set in t50 to t51 is met. The Condition set in t32 to t33 must be active when the timer is reached for the output state to change.

In the case of the Off delay timer, once the output state is on, it will delay turning of f after the Off delay value is reached on t52 to t53. When the Off delay time is reached, the condition set in t32 to t33 must still be off.

4.7 Reflected Wave Protection

When more than one motor is connected to one inverter, total wiring length should be less than 200m (656ft). Do not use a 3-wire cable for long distances. Due to increased leakage capacitance between wires, over-current protective feature may operate or equipment connected to the output side may malfunction. In case of long wire length, lower carrier frequency or contact Baldor for recommendations.

CHAPTER 5

Control Wiring

This chapter describes how to wire the signal and I/O terminal strip for stop, speed feedback, and remote control signals.

ATTENTION:Apply the rated torque to terminal screws. Loose screws can cause short circuit and malfunction. Tightening the screws too much

can damage the terminals and cause short circuit and malfunction.

ATTENTION:Make sure the input power is off before wiring. ATTENTION:After power supply is switched off following operation, wait

at least 10 minutes after LED keypad display is off before you start working on it.

ATTENTION:Applying input power supply to the output terminals U, V and W causes internal inverter damage.

ATTENTION:Use ring terminals with insulated caps when wiring the input power and motor wiring.

ATTENTION:Do not leave wire fragments inside the inverter. Wire fragments can cause faults, breakdowns and malfunctions.

ATTENTION:When more than one motor is connected to one inverter, total wiring length should be less than 200m (656ft). Do not use a 3-wire cable for long distances. Due to increased leakage capacitance between wires, over-current protective feature may operate or equipment connected to the output side may malfunction. In case of long wire length, lower carrier frequency or contact Baldor for recommendations.

ATTENTION:Never short B1 and B2 terminals. Shorting terminals may cause internal inverter damage.

ATTENTION:Do not install a power factor capacitor, surge suppressor or RFI filter in the output side of the inverter. Doing so may damage these components.

5.1 Stop Circuit Requirements

ATTENTION:You must provide an external, hardwired emergency

stop circuit outside of the drive circuitry. This circuit must disable the

In addition to the operational stop, you must provide a hardwired emergency stop external to the drive. The emergency stop circuit must contain only hardwired electromechanical components. Operation of the emergency stop must not depend on electronic logic (hardware or software) or on the communication of commands over an electronic network or link. Note that the hardwired emergency stop you install can be used at any time to stop the drive.

system in case of improper operation. Uncontrolled machine operation can result if this procedure is not followed. Failure to observe this precaution could result in bodily injury.

5.2 Motor Start/Stop Precautions

ATTENTION:A contactor or other device that routinely disconnects and

reapplies the AC line to the drive to start and stop the motor can cause

Important points to remember about I/O wiring:

• Always use copper wire.

• Wire with an insulation rating of 600V or greater is recommended.

• Control and signal wires should be separated from power wires by at least 0.3

meters (1 foot).

drive hardware damage. The drive is designed to use control input signals that will start and stop the motor. If used, the input device must not exceed one operation per minute or drive damage can occur. Failure to observe this precaution can result in damage to, or destruction of, equipment.

ATTENTION:The drive start/stop control circuitry includes solid-state components. If hazards due to accidental contact with moving machinery or unintentional flow of liquid, gas or solids exist, an additional hardwired stop circuit may be required to remove the AC line to the drive. When the AC line is removed, there will be a loss of any inherent regenerative braking effect that might be present - the motor will coast to a st op . A n a ux iliary brakin g method may b e required.

Important: I/O terminals labeled “Common” are not referenced to the safety ground

terminal and are designed to greatly reduce common mode interference.

ATTENTION:Driving the 4-20 mA analog input from a voltage source could cause component damage. Verify proper configuration prior to

applying input signals.
