DigIn TermBlk 02/
Start/Run FWD
Run FWD
Used to initiate motion and also can be used as a programmable digital input. It can be programmed with t062 [DigIn
TermBlk 02] as three wire (Start/Dir with Stop) or two wire (Run FWD/Run REV) control. Current consumption is 6 mA.
t063
03
DigIn TermBlk 03/
Dir/Run REV
Run REV
Used to initiate motion and also can be used as a programmable digital input. It can be programmed with t063 [DigIn
TermBlk 03] as three wire (Start/Dir with Stop) or two wire (Run FWD/Run REV) control. Current consumption is 6 mA.

05
DigIn TermBlk 05/
Pulse In
Preset Freq
Program with t065 [DigIn TermBlk 05]. Also functions as a Pulse Train input for reference or speed feedback. The
maximum frequency is 100 kHz. Current consumption is 6 mA.
t065
06
DigIn TermBlk 06
Preset Freq
Program with t066 [DigIn TermBlk 06]. Current consumption is 6 mA.
t066
11
+24V DC
–
Referenced to Digital Common. Drive supplied power for digital inputs. Maximum output current is 100 mA.
–
12
+10V DC
–
Referenced to Analog Common. Drive supplied power for 0...10V external potentiometer.
Maximum output current is 15 mA.

0-10V In
(1)
(1) Only one analog frequency source may be connected at a time. If more than one reference is connected at the same time, an undetermined frequency reference will result.
Not Active
For external 0-10V (unipolar) input supply or potentiometer wiper.
Input impedance: Voltage source = 100 kW
Allowable potentiometer resistance range = 1...10 kW
