(4) Overhanging Loads
A servomotor may not be operated with an overhanging load, which tends to continuously rotate the motor. Fig.
4.1 shows a typical example of such a load.
• DO NOT use the servomotor with the Vertical Axis Motor Drive without Counterweight
• DO NOT use the servomotor with the Feeding Motor Drive
Fig 4.1 Examples of Overhanging Loads
• Never operate servomotors with an overhanging load. Doing so will cause the SERVOPACKs’ regenerative
brake to be applied continuously and the regenerative energy of the load may exceed the allowable range
causing damage to the SERVOPACK.
• The regenerative brake capacity of the SGDM SERVOPACKs is rated for short-term operation
approximately equivalent to the time it takes to decelerate to a stop.
