11 Analog Input (Option)
11.1 Function
For the digital servo amplifier JetMove 204-480, an optional integrated analog input
card can be ordered (article designation of the device: JM-204-480...-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. In this case, a pressure sensor in the machine
connected to the analog input of the JetMove would deliver the actual pressure value
to the control loop.
