n Using External Power Supply (Sink Mode)
The high voltage level of the pulse output signal depends on the external voltage applied. The voltage must be between 12
and 15 Vdc. The load resistance must be adjusted so that the current is lower than 16 mA.

u Terminal A2 Input Signal Selection
Terminal A2 can be used to input either a voltage or a current signal. Select the signal type using switch S1 as explained in
Table 3.14 . Set parameter H3-09 accordingly as shown in Table 3.15 .
Note: If terminals A1 and A2 are both set for frequency bias (H3-02 = 0 and H3-10 = 0), both input values will be combined to create the frequency
reference.
Table 3.14 DIP Switch S1 Settings
Setting Description
V (left position) Voltage input (-10 to +10 V or 0 to 10 V)
I (right position) Current input (4 to 20 mA or 0 to 20 mA): default setting

H3-09 Terminal A2 signal level selection
Selects the signal level for terminal A2.
0: 0 to 10 Vdc
1: -10 to 10 Vdc
2: 4 to 20 mA
3: 0 to 20 mA
0 to 3 2
u Terminal A3 Analog/PTC Input Selection
Terminal A3 can be configured either as multi-function analog input or as PTC input for motor thermal overload protection.
Use switch S4 to select the input function as described in Table 3.16 .
Table 3.16 DIP Switch S4 Settings
Setting Description
AI (lower position) (default) Analog input for the function selected in parameter H3-06
PTC (upper position) PTC input. Parameter H3-06 must be set to E (PTC input)
