JetMove 208-480 11.1 Description
Jetter AG 89
11 Analog Input (Option)
11.1 Description
For the digital servo amplifier JetMove 208-480, an optional integrated analog input
card can be ordered (article designation of the device: JM-208-480...-IA1). This card
supplies an analog input of a 12-bit resolution. The converted value of the measured
voltage can be read by a register of the JetMove in the PLC program or processed
by the firmware of the JetMove in an additional controller. This way it is possible for
example, to realize a pressure control loop in which the motor controlled by the
JetMove generates the pressure. A pressure sensor in the machine is connected to
the analog input of the JetMove to deliver the actual pressure value for the control
loop.
