(1) Servo amplifiers and servo motors used
Use the following models of servo amplifiers and servo motors:
Servo amplifier series: SGMAS 

(2) Installation
Install a fan of 100CFM (2.8m3/min) air flow 4in (10.16cm) above the servo amplifier or provide cooling of at least equivalent capability.

(3) Short circuit rating
Having been subjected to UL tests in the alternating-current circuit whose peak current is limited to 5000A or less, this servo amplifier conforms to this circuit.

(4) Capacitor discharge time
The capacitor discharge time is as listed below. To ensure safety, do not touch the charging section for
15 minutes after power-off.

 

 

(5) Options and auxiliary equipment Use products which conform to the UL/C-UL Standard.

 

(6) Attachment of a servo motor
For the flange size of the machine side where the servo motor is installed, refer to “CONFORMANCE
WITH UL/C-UL STANDARD” in the Servo Motor Instruction Manual.

 

(7) About wiring protection
For installation in United States, branch circuit protection must be provided, in accordance with the
National Electrical Code and any applicable local codes.
For installation in Canada, branch circuit protection must be provided, in accordance with the Canada
Electrical Code and any applicable provincial codes.

 

 

 

 

Standard (Non-Time Delay, Single Element) Fuses
Standard fuses protect against short circuits and ground faults using thermal features to sense a heat
buildup in the circuit. Once blown standard fuses are no longer usable and must be replaced..

 

 

 

 

 

NEMA design A and B motors up to 500 hp in size are required to have a full-load efficiency value (selected froma table of nominal efficiencies) stamped on the nameplate. Most analyses of motor energy conservation savingsassume that the existing motor is operating at its nameplate efficiency. This assumption is reasonable above the50% load point as motor efficiencies generally peak at around 3/4 load with performance at 50% load almostidentical to that at full load. Larger horsepower motors exhibit a relatively flat efficiency curve down to 25% of fullload.

 

It is more difficult to determine the efficiency of a motor that has been in service a long time. It is not uncommon for the nameplate on the motor to be lost or painted over. In that case, it is almost impossible to locate efficiency information. Also, if the motor has been rewound, there is a probability that the motor efficiency has been reduced.

 

When nameplate efficiency is missing or unreadable, you must determine the efficiency value at the operating load point for the motor. If available, record significant nameplate data and contact the motor manufacturer. With the style, type, and serial number, the manufacturer can identify approximately when the motor was manufactured.

Often the manufacturer will have historical records and can supply nominal efficiency values as a function
of load for a family of motors.

 

When the manufacturer cannot provide motor efficiency values, you may use estimates from Attachment C.
Attachment C contains nominal efficiency values at full, 75%, 50%, and 25% load for typical standard efficiency motors of various sizes and with synchronous speeds of 900, 1200, 1800, and 3600 rpm. Attachment C indicates“industry average” full- and part-load performance for all standard efficiency motors currently on the market.

 

Three steps are used to estimate efficiency and load. First, use power, amperage, or slip measurements to
identify the load imposed on the operating motor. Second, obtain a motor part-load efficiency value consistent with the approximated load either from the manufacturer or by interpolating from the data supplied in Attachment C. Finally, if direct-read power measurements are available, derive a revised load estimate using both the power measurement at the motor terminals and the part-load efficiency value as shown in Equation 8.
