3.3 Supported functions
System functions
F-TM ServoDrive supports the following PROFINET IO functions:
● Firmware update via PROFINET IO
F-TM ServoDrive supports the function:
● Identification data I&M 0 to 3
PROFIdrive communication types
The F-TM Servo Drive supports the following types of communication:
● Cyclic data exchange via a cyclic data channel
Motion control systems require cyclically updated data during operation for open-loop and
closed-loop control. This data must be sent as setpoints to the drive devices or read as
actual values from the drive devices via the communication system. The transfer of this
data is normally time-critical.
● Acyclic data exchange via an acyclic data channel
An acyclic parameter channel for exchange of parameters between the CPU or
supervisor and the drive devices is additionally available. Access to this data is not time-
critical.
● Alarm channel
Alarms are output event-triggered and indicate incoming and outgoing error states.
PROFIdrive application classes
The F-TM ServoDrive supports Application Classes 1 and 4 of the PROFIdrive profile as of
V4.2.
● Class 1 (AC1)
The drive is controlled via a speed setpoint using PROFINET.
The closed-loop speed control takes place entirely in the drive.
Typical applications are, for example, simple frequency converters for pump and fan
control.
● Class 4 (AC4)
This PROFIdrive application class defines a speed setpoint interface with the closed-loop
speed control taking place in the drive and the closed-loop position control taking place in
the CPU, as is required for robot and machine tool applications with coordinated motion
sequences on multiple drives.
