Trim-

Trim+

Description

Sets the internal differential counter and the analog correction signal to zero. Both drives run solely in analog synchronization (open loop) whilst activated

Provides a temporary lower or higher slave speed which results in a phase displacement between the motor shafts. When releasing the trim command, the drives will synchronize again in their new relative position. In Modes 5 and 6 impulses are required to change the position step by step

4 n. a.

5 n. a.

6 Integrator off This command sets the phase integrator to 0. This prevents the integrator from building up error when the drives are stopped, but not in a perfect synchronous position. This prevents any leap in speed on restart

7 Store EEProm Stores actual operational settings to the EEProm, so they remain available also after power down.

8 Scroll Display Selects the source of the digital display.

See chapter 9.3

“Display of Actual Values” for details.

9 Parameter

Disable

Disables the keypad for any parameter access. Only commands assigned to the keypads will be accessible

10 Clear

Min. & Max

11 Index Slave Assigns the index pick-up function to the input

12 Index Master (respectively Factor1 inc./dec. with Mode 4)

13 n. a.

Sets the internal minimum and maximum error registers to the actual differential error.

14 Read

Thumbwheels

15 Stop Slave Ramps the Slave drive down to standstill using the

“Stop Ramp”. When released, the Slave ramps up again and locks into synchronization

16 n. a. n. a. = not applicable

Reads and activates the Factor 1 setting from the front thumbwheel switches (model BY641 only)
