4.8 Control connections
4.8.1 Control terminal connections
The functions of the control terminals can be set using parameters or via Marshal. The default connections are suitable for basic motor speed control
using analog inputs to define a frequency reference.
For wiring diagrams of the non-default configurations, refer to section 6.2
Controlling the motor speed . or find the diagrams embedded within Marshal.
Figure 4-14 Default control terminal connections
The 0 V terminals are internally connected ground/earth and cannot be disconnected. An external controller ground or reference should be connected
directly to the drive 0 V reference terminals (T3, T5, T10). If more 0 V connections are required, a local terminal block placed next to the drive and
close to the I/O port should be used. External modules that interact with the I/O of the drive should avoid connecting their references to the cabinet or
the ground bar, direct connections should be used instead.
The voltage rating of the relay cables should be suitable for the maximum expected voltage.
If any of the digital inputs are connected in parallel with an inductive load (i.e. contactor or motor brake) then suitable suppression (i.e.
diode or varistor) should be used on the coil of the load. If no suppression is used then over voltage spikes can cause damage to the digital
inputs and outputs on the drive
CAUTION
The control connections shown above and the 485 port can be PELV rated when connected within a PELV circuit. The terminals are not
PELV rated if the relay is connected to a circuit exceeding Overvoltage Category II.
