SGDG Legend - YAI

200V 3P/1P 1.0kW

The SGDG Legend servo amplifier is a legacy product and no longer promoted in the Americas. The SGDG Legend was a single-phase or three-phase AC and DC input amplifier with 100% digital design, an intelligent serial coder and ethernet motion control functionality. Four amplifier sizes (100w - 1,500w) and 23 motor choices cover a wide range of needs.

Question	Posted Date
When is it necessary to connect an external regen resistor to the SGDG LEGEND amplifier? Posted Date: 01/21/2002 Answer: Install an external regen resistor if the regenerative power from the load exceeds the processing capability of the LEGEND amplifier (usually associated with alarm #3: regen circuit error). Connect the resistor to terminals B1 and B2 on the Legend amplfier. On 1kW and 1.5 kW amplifiers, remove the jumper wire between B2 and B3 . Turn OFF #5 of SW 1 to disable the regen overload alarm. When the regen alarm is disabled, be sure the resistor has enough capacity (after proper derating) to dissipate the regen energy of the load. Refer to section 4.5 of the LEGEND Digital Torque Amplifier SGDG User's Manual for more details.

What voltage levels will cause an overvoltage or undervoltage alarm? Posted Date: 02/06/2009 Answer: All Yaskawa Sigma and LEGEND series amplifiers input power specifications are +10% to -15%. 10% above the highest voltage input specified will cause an overvoltage alarm, while 15% below the lowest voltage specified will cause an undervoltage alarm. For a 100-115 amplifier +10% / -15% equates to 85 VAC and 126 VAC respectively. For a 200-230 amplifier +10% / -15% equates to 170 VAC and 253 VAC respectively. For a 400-480 amplifier +10% / -15% equates to 340 VAC and 528 VAC respectively.

Is there a recommended solution for controlling a motor brake when the system has a LEGEND Amplifier? Posted Date: 02/15/2006 Answer: Yes, the circuit for controlling the servomotor's brake is very simple. It utilizes the LEGEND Alarm output, the SMC3010 Estop output, and one (1) SMC3010 digital output. If a fault occurs in the LEGEND amplifier, its Alarm output will turn off, engaging the motor's brake. If a fault occurs within the SMC3010, its Estop output will turn off, engaging the motor's brake. The programmable digital output gives the program control of the motor's brake.

Is it possible to isolate or split the encoder output signal from an SGDH PG output? Posted Date: 07/13/2004 Answer: Yes, the best way to split the encoder output signal from an SGDH amplifier (i.e. connecting the PG output to multiple receivers) is to use a differential signal splitter. BEI Technologies sells an Optically Isolated Encoder Driver Module (three channels Differential) which does the following: 1. Provides optical isolation of three complimentary signals (A & /A, B & /B, Z & /Z) 2. Allows PG connections up to 500 ft. in length 3. Allows encoder splitting to up to 8 receivers BEI has produced the attached document which contains more information about this product.

Is it possible to add external regen resistors to the SGDG LEGEND amplifiers? Posted Date: 08/13/2002 Answer: Yes. External regen resistor can be added to the SGDG-10GT and SGDG-15GT by connecting it across terminals B1 & B2. Switch SW1-5 should be turned OFF when external regen resistor is added. The LEGEND SGDG-01GT & SGDG-04GT needs special attention when external regen resistor is required in the appication. External regen unit JUSP-RG08D must be used with the SGDG-01GT. The JUSP-RG08D is a self-contain unit consisting of DC bus sensing and alarm circuitry, switching IGBT, and a 50 ohm regen resistor. The JUSP-RG08D can also be used with the SGDG-04GT, or the user can order the SGDG-04GTY22P for regen applications only. The SGDG-04GTY22P must have two (2) RH500N25_ohmK resistors wired in series connected to it at all times. See attached document, eng02.027MCD, for more details.

Does the LEGEND amplifier have a circuit for a brake? Posted Date: 10/20/2006 Answer: The LEGEND Amplifier (SGDG) has been designed for high performance torque control. To improve the cost effectiveness, many I/O points and functions (including the Mechanical Brake Control Circuit) have been eliminated when compared to the SGDH. For this reason, the mechanical brake control circuit functionality must be handled in the upper controller or PLC.

Can the linear encoder be mounted "backwards" (positive direction of linear encoder opposite to positive direction of linear motor)? Posted Date: 04/28/2003 Answer: Yes, the linear encoder can be mounted "backwards" relative to the linear motor, it is good design practice to insure that the motor and encoder have the same positive direction reference. Normally, the linear motor and encoder would be oriented such that the positive direction of each is in the same direction. The positive direction of the linear motor is in the direction in which the motor cables/connectors protrude. Generally, this holds true for the linear encoder as well (as it does for Renishaw and Heidenhain). Please consult the linear encoder manufacturer in regards to positive orientation. If the linear encoder is mounted "backwards" relative to the linear motor, one of the following MUST be done in order for the linear motor system to function properly. 1. Rewire the linear encoder cable. Swap the "A" signal wires with the corresponding "B" signal wires. 2. The following is only applicable for Sigma II SGDH type servo amplifiers with the Y213 modification (Y213 modification is for use with linear motors only). Set user parameter Pn080.1=1 (B-phase progression). This will allow for proper commutation of the linear motor. However, the positive direction of the motor will now be in the direction opposite in which the motor cables/connectors protrude. To change the motor direction, set Pn000.0=1. 3. The following is only applicable for Legend SGDG type servo amplifiers. Set SW1 function selection switch no.4 (Linear Scale Polarity Reversal) to OFF (B-phase progression). This will allow for proper commutation of the linear motor. However, the positive direction of the motor will now be in the direction opposite in which the motor cables/connectors protrude. To change the motor direction, set SW1 function selection switch no.6 (Feedback Pulse B-phase Reversal) to OFF.

Can the LEGEND amplifier accept a 5VDC input to enable the motor? Posted Date: 10/31/2002 Answer: Yes. The LEGEND amplifier (SGDG) is equipped with 24VDC input (CN1-14) and 5VDC (CN1-26) for enabling the servo. Either input may be wired. Note: When the LEGEND-MC is used in combination with the LEGEND Series amplifiers, it is not necessary to wire the servo enable input to the amplifier. It is recommended that the servo enable be controlled through the LEGEND-MC.
