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.
5.2.6.1 Load Sharing Setup Example
1. The Master and Follower VFDs must be set to Flux Vector control method, A01-02 = 3.
2. The Master VFD requires a ±10 VDC output with H04-01 or H04-04 = 109 — “Torque Reference”.
3. The Master VFD analog output gain (H04-02 or H04-05) should be = 50%.
4. The Master VFD requires H02-0x = 2A — “During RUN 2”.
5. The Follower VFD requires H01-xx = 66 — “Load Share”.
6. The Follower VFD requires a ±10 VDC input with H03-06 or H03-10 = 13 — “Torque Reference”.
7. The Follower VFD analog input gain (H03-07 or H03-11) should be = 200%.
8. OPTIONAL: The Master VFD can be set to H01-xx = 68 — “LodShr Ready Run”, and then the Follower VFD
can be set to H02-0x = 0 — “Brake Release.”
5.2.7 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 VFD will use the stopping method programmed in C03-12 and
display the KLX Klixon alarm. The VFD will resume normal operation when the motor cools down and a new RUN
command is applied.
