■ F1-51: PG-F3 PGoH Detection Level
No.

F1-51
(03D3)
PG-F3 PGoH Detection
Level
The drive will detect PGoH [Encoder (PG) Hardware Fault] if the value of this parameter is
smaller than the value of .
80%
(1 - 100%)
The drive will detect PGoH if the value of this parameter is smaller than the value of .
Regarding the expression , Sin θ is the single-track (phase B) output from the encoder and Cos θ
is the single-track (phase A) output from the encoder.
Note:
This function is enabled when F1-20 = 1 [Encoder 1 PCB Disconnect Detect = Enabled].
■ F1-52: Serial Encoder Comm Speed
No.

F1-52
(03D4)
Serial Encoder Comm
Speed
Sets the communication speed between the PG-F3 option and the serial encoder.
0
(0 - 2)
Note:
This function is enabled when F1-50 = 1 or 2 [PG-F3 Option Encoder Type = EnDat Serial Only or HIPERFACE].

◆ F2: Analog Input Option
F2 parameters set the operation of the drive when you use analog input option card AI-A3. The AI-A3 card has 3
input terminals that accept voltages of -10 V to +10 V (20 kΩ) or currents of 4 mA to 20 mA (250 Ω). Install the
AI-A3 card to enable setting very accurate analog references with high resolution.
Refer to the AI-A3 option manual for more information about how to install, wire, and set the AI-A3 card.
WARNING! Sudden Movement Hazard. Do test runs and examine the drive to make sure that the command references are
correct. If you set the command reference incorrectly, it can cause damage to the drive or serious injury or death.
■ F2-01: Analog Input Function Selection

Analog Input Function
Selection
Sets the input method for the analog reference used with AI-A3.
0
(0, 1)
Note:
When the AI-A3 card is not mounted in the drive, analog input terminals A1 to A3 on the drive are always enabled. The setting of this
parameter does not have an effect.
0 : 3 Independent Channels
Set F2-01 = 0 to increase the precision of A/D conversion when you use the functions for terminals A1 to A3 on
the drive as they are. You can input the MFAI signal from terminals V1 through V3 for AI-A3. The functions for
terminals A1, A2, and A3 on the drive are sent to terminals V1, V2, and V3 for AI-A3. Use gain and bias
adjustment when you input current to set signals to have negative numbers.
Note:
• Set b1-01 = 1 [Frequency Reference Selection 1 = Analog Input] to set inputs individually.
• If F2-01 = 0 and b1-01 = 3 [Option PCB], the drive will detect oPE05 [Run Cmd/Freq Ref Source Sel Err].
Figure 12.77 shows the individual input of analog inputs. H3-xx parameters set the function to input the analog
reference received from the AI-A3 card and to adjust the gain and bias of these signals.
