Two relay outputs are available:
- terminals 26, 27, 28: relay RL1; reverse contact (250 VAC, 3A; 30 VDC, 3A)
- terminals 29, 30, 31: relay RL2; reverse contact (250 VAC, 3A; 30 VDC, 3A)
Parameters P61 (RL1 Opr) and P62 (RL2 Opr) in the Digital Output submenu affect the relay output
functionality. Relay energizing and de-energizing may be delayed through the following parameters:
- P65 RL1 Delay ON
- P66 RL1 Delay OFF
- P67 RL2 Delay ON
- P68 RL2 Delay OFF
Factory-setting is as follows:
RL1: relay “ready” (terminals 26, 27 and 28); energizes when the inverter is ready to supply the motor.
At power on, the equipment takes some seconds before initializing; the relay energizes when an alarm trips. The
alarm trip locks the inverter.
RL2: “frequency/speed threshold” relay (terminals 29, 30 and 31); energizes when the output frequency (IFD
SW) or the motor speed (VTC SW) attains the level set through the "Digital Output" menu (parameters P73 "RL2
level", P74 "RL2 Hyst.").
CAUTION Never exceed max. voltage and max. current values allowed by relay contacts.
CAUTION
Use freewheeling diode for DC inductive loads.
Use antidisturbance filters for AC inductive loads.
10.4. Analog Output Features (Terminals 17 and 18)
Two analog outputs are located on terminal 17 and terminal 18. Analog outputs may be used to connect
additional devices or to generate a signal to be sent to other devices. Some particular configuration jumpers
located on control board ES778 allow selecting the type of output signal (0-10V, 4-20mA or 0-20mA).

Through the OUTPUT MONITOR menu, set the quantity for the analog output and the ratio between the value
of the output signal and the measured quantity.
The ratio between the output signal and the measured quantity is expressed as the ratio between the quantity
value and the relevant voltage value on the analog output (e.g. Hz/V for IFS SW). When setting the jumpers to
configure the output as 4-20mA or 0-20mA, multiply by 10 the value set to obtain the quantity value when the
output delivers 20mA (e.g.: if P32=10Hz/V, the analog output will deliver 20mA when the inverter delivers
100Hz).
CAUTION
Never deliver input voltage to analog outputs. Do not exceed max. allowable
current.
