AN[N] – Analog input array
Purpose:
AN[1] reports the analog input #1 value after offset correction (AS[1]), in volts.
AN[2] reports the analog input #2 value after offset correction (AS[2]) in volts,
for products that support a second analog input.
AN[3] … AN[5] – see table below.
AN[6] reports the DC line voltage value, in volts. Note that for AC products,
this value is after rectification. For example, with 1-phase 220 VAC supply,
expect AN[6]=
√2x220=310 V. with 3-phase 380 VAC L-L supply, expect
AN[6]= √2x380=540 V.
AN[7] reports the duty cycle value of the PWM signal after offset correction in
fractional units.
Attributes: Type: Status report, Real
Source: Program, RS-232, CANopen
Restrictions: None
Unit modes: All
SimplIQ: Modified
AN[3..5] read motor phase currents, in Amperes. The meaning depends on the motor
type
2-phase (stepper)
AN[3] Phase A
AN[4] Phase B
AN[5] 0
Typical applications:
1. Reading external sensors that provide ±10 V.
2. Reading analog or PWM references for either velocity or current.
3. Reading phase currents and line voltage.
Notes:
Analog input #1 serves as reference input for analog torque or analog
velocity command while in auxiliary reference mode (RM=1).
Different SimplIQ drives support a different number of analog inputs. For
specific details consult the drive’s Installation Guide.
