Hi
@Gerrit-S, if you want to reference the motor without opening the brake, just send mode 300 in PO6 and activate bit 7 in PO1. In PO1, bits 0,1 must be off, the brake will not open. If you activate them, the motor will be held in place by current. Bit 13 can be off the whole time during referencing.
As already mentioned in the discussion, if you are going to make a modulo application, you must set the drive train gear ratio as a fractional form. If you have a SEW gearbox, you just need to find it in the program. MOVISUTIE knows all gear ratios of SEW gearboxes in fractional form. If you are making settings for a foreign gearbox, you need to write it down as in the picture. Or. ask the gearbox manufacturer for the entire gear ratio in fractional form. If you write the value in decimal form of the converter, the error increases after each revolution and since you do not have an integer portion. With each revolution of the gearbox, 1222.3333 increments are counted, the error then increases.
If you have, for example, infinite movement, the chain is 2m for a full revolution, you set the modulo max to 2m and send the desired position 2m, the converter will fall into an error in modulo mode. You must not send the desired position as modulo max. In this case, if you want, for example, to do a full cycle of the chain send 1m and then 0m. The chain will go the whole way and at the end your current position will be 0 again. If you don't have a reference sensor on the track. Use this setting index 8509.11 calculate target position from current position.
