other special functions. If this is not the case, each inverter may try to move or decelerate at a
different speed placing extra strain on the drive train and potentially resulting in a speed deviation
fault.
NOTE :
1. The Limit Switch stopping method is not selectable in Load Sharing mode. If a Stop Limit is
input, the output is turned off and the brake output will set immediately.
2. Weight Limit Input (H01-xx = 12 or 62) — Upper Limit 3 is always active regardless of the setting
of parameter C03-11.
Minimum Programming Requirement for “Load Sharing” Operation
1. The Master and Slave drives must be set to Flux Vector control method, A01-02 = 3.
2. The Master drive requires a ±10 VDC output with H04-01 or H04-04 = 109 — “Torque Reference”.
3. The Master drive analog output gain (H04-02 or H04-05) should be = 50%.
4. The Master drive requires H02-0x = 2A — “During RUN 2”.
5. The Slave drive requires H01-xx = 66 — “Load Share”.
6. The Slave drive requires a ±10 VDC input with H03-06 or H03-10 = 13 — “Torque Reference”.
7. The Slave drive analog input gain (H03-07 or H03-11) should be = 200%.
8. OPTIONAL: The Master drive can be set to H01-xx = 68 — “LodShr Ready Run”, and then the
Slave Drive can be set to H02-0x = 0 — “Brake Release.”
Klixon
The Klixon Multi-Function input is intended for motors that have a Motor Thermal Overload Switch.
Klixon is usually embedded in the motor windings and changes state when the motor reaches a
certain temperature. When a multi-function input (H01-0x = 56 or 57) is active, the drive will use the
stopping method programmed in C03-12 and display the KLX Klixon alarm. The drive will resume
normal operation when the motor cools down and a new RUN command is applied.
