02 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.
t063
04 Digital Common – Return for digital I/O. Electrically isolated (along with the digital I/O) from the rest of the drive. –
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.

(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

15 4-20mA In
(1)
Not Active For external 4-20 mA input supply.
Input impedance = 250 W

C1 C1 – This terminal is tied to the RJ-45 port shield. Tie this terminal to a clean ground in order to improve noise immunity
when using external communication peripherals.
–
C2 C2 – This is the signal common for the communication signals. –
