Control Card, RS-485 serial communication
Terminal number
Terminal number 61
The RS-485 serial communication circuit is functionally separated from other central circuits and
galvanically isolated from the supply voltage (PELV).
Control Card, 24 V DC output
Terminal number
Output voltage
Max. load
The 24 V DC supply is galvanically isolated from the supply voltage (PELV), but has the same potential
as the analog and digital inputs and outputs.
Control Card, 10 V DC output
Terminal number
Output voltage
Max. load
The 10 V DC supply is galvanically isolated from the supply voltage (PELV) and other high-voltage
terminals.
Control card, USB serial communication
USB standard
USB plug
Connection to PC is carried out via a standard host/device USB cable. The USB connection is
galvanically isolated from the supply voltage (PELV) and other high-voltage terminals. The USB ground
connection is not galvanically isolated from protection ground. Use only an isolated laptop as PC
connection to the USB connector on the adjustable frequency drive.
Control Characteristics
Resolution of output frequency at 0-590 Hz
Repeat accuracy of Precise start/stop (terminals
18, 19)
System response time (terminals 18, 19, 27, 29,
32, 33)
Speed control range (open-loop)
Speed accuracy (open-loop)
All control characteristics are based on a 4-pole asynchronous motor

8.7 Connection Tightening Torques

Apply the correct torque when tightening fasteners in the locations that are listed
in Table 8.25 and Table 8.26. Too low or too high torque when fastening an electri-
cal connection results in a bad electrical connection. To ensure correct torque, use
a torque wrench.
