9.6.3.8 Tachometric, Alarm and Filter Output
The analogue output channel is configured, by default, to provide a tachometric output signal.
The tachometric output is a 0 to 5V PWM waveform at 1KHz (for DDMP 1.05kW -1-Ph only).
The tachometric output is a 0 to 10V PWM waveform at 1KHz (for all other fans).
when the speed is equal or higher than the speed min and it is 0% when the speed is lower.
The device reading the output must be connected to TACHO\ALARM\FILTER pin and GND.
The max current supplied of the output is 0.2mA.
Remember that the Speed
Real
is 0 whenever the required speed is lower than Speed
min
unless the fan is in the dragging
phase.
9.6.3.7 Relay (for DDMP 2.65kW - 3-Ph only)
A relay is available on the Three-Phase drivers.
It is suitable for 250Vac/30Vdc 5A.
When the driver is powered off the relay is open -> the PCB label
indicates C-NO.
During the functioning the relay is Normally Closed in No-Alarm
condition and open in case of alarm.

(22 - 14 AWG) solid or stranded cable.
The same analogue output channel can be reconfigured, by changing the value in Holding Register 46 (see paragraph 17.3 at page
54), as a Digital Alarm Output (refer to chapter 18 and paragraph 18.4), or in one of the alternative alarm modes described in pa -
ragraphs 11.1 and 11.2.
