Power zero b2 and control zero b12 must be jumpered. If removing power pack, < 1 m directly to DIN plug. If removing > 1 m route control zero separately to ground. Notes for calibrating the P.C.B.s Zero: A setpoint U � 300 mV is set as default for calibration. E Sensitivity (max.): A setpoint U = 10 V is set as default for calibration. E Notes on the use of ramps Ramp UP (accelerate) and ramp DOWN (decelerate) are each set by a trimming potentiometer. Ramp ON, if b20 open. Ramp OFF, if b20 U > 6 V, e.g. 10 V from b22. Ramp OFF interrupts a ramp in progress. There is an abrupt transition to the final signal value. 6/6 Bosch Rexroth AG Hydraulics VT-VSPA1 RE 30109/07.05 Unit dimensions (nominal dimensions in mm) Plug to DIN 41612–F32 Amplitude Dither Bosch Rexroth AG © This document, as well as the data, specifications and other information Hydraulics set forth in it, are the exclusive property of Bosch Rexroth AG.
