Description

Default

(Range)

F1-11

(038A)

Speed Deviation Detect
DelayTime

Sets the length of time that the difference between the frequency reference and speed feedback must
be more than the level in

F1-10

to cause

dEv [Speed Deviation]

Note:

A1-02 = 0 [Control Method Selection = V/f]

, you must set

H6-01 = 3 [Terminal RP Pulse

Train Function = Speed Feedback (V/F Control)]

to enable this parameter.

0.5 s

(0.0 - 10.0 s)

F1-12

(038B)

Encoder 1 Gear Teeth 1

Sets the number of gear teeth on the motor side. This parameter and

F1-13 [Encoder 1 Gear Teeth 2]

set the gear ratio between the motor and encoder.

(0 - 1000)

F1-13

(038C)

Encoder 2 Gear Teeth 1

Sets the number of gear teeth on the load side. This parameter and

F1-12 [Encoder 1 Gear Teeth 1]

set the gear ratio between the motor and encoder.

(0 - 1000)

F1-14

(038D)

Encoder Open-Circuit Detect
Time

Sets the length of time that the drive must not receive a pulse signal to cause

PGo [Encoder (PG)

Feedback Loss]

Note:

Motor speed and load conditions can cause

ov [Overvoltage]

and

oC [Overcurrent]

faults.

A1-02 = 0 [Control Method Selection = V/f]

, you must set

H6-01 = 3 [Terminal RP Pulse

Train Function = Speed Feedback (V/F Control)]

to enable this parameter.

2.0 s

(0.0 - 10.0 s)

F1-17

(03AC)

Deviation 2 Detection
Selection

Usually it is not necessary to change this setting. Sets the number of motor rotations that the drive
will detect more than one Z pulse per rotation to detect

dv2

(0 - 100)

F1-18

(03AD)

Deviation 3 Detection
Selection

Sets the number of rotations necessary to detect conditions that invert the torque reference and rate of
acceleration and cause

dv3 [Inversion Detection]

(0 - 10)

F1-19

(03AE)

Deviation 4 Detection
Selection

Sets the number of pulses necessary to cause

dv4 [Inversion Prevention Detection]

128

(0 - 5000)

F1-20

(03B4)

Encoder 1 PCB Disconnect
Detect

Sets the function that enables and disables detection of a disconnected encoder connection cable to
cause

PGoH [Encoder (PG) Hardware Fault]

0 : Disabled

1 : Enabled

(0, 1)

F1-21

(03BC)

Encoder 1 Signal Selection

Sets the number of channels for the signal to the encoder option card.

0 : A Pulse Detection

1 : AB Pulse Detection

(0, 1)

F1-30

(03AA)

Motor 2 Encoder PCB Port
Select

Sets the drive port to install the motor 2 encoder option card.

0 : CN5-C

1 : CN5-B

(0, 1)

F1-31

(03B0)

Encoder 2 Pulse Count
(PPR)

Sets the number of output pulses for each motor revolution for motor 2.

1024 ppr

(1 - 60000 ppr)

F1-32

(03B1)

Encoder 2 Rotation Selection

Sets the output sequence for the A and B pulses from the encoder for motor 2. This parameter
assumes that the motor is operating in the forward direction.

0 : Pulse A leads in FWD Direction

1 : Pulse B leads in FWD Direction

(0, 1)

F1-33

(03B2)

Encoder 2 Gear Teeth 1

Sets the number of gear teeth on the motor side for motor 2. This parameter and

F1-34 [Encoder 2

Gear Teeth 2]

set the gear ratio between the motor and encoder.

(0 - 1000)

F1-34

(03B3)

Encoder 2 Gear Teeth 2

Sets the number of gear teeth on the load side for motor 2. This parameter and

F1-33 [Encoder 2

Gear Teeth 1]

set the gear ratio between the motor and encoder.

(0 - 1000)

F1-35

(03BE)

Encoder 2 Pulse Monitor
Scaling

Sets the ratio between the pulse input and the pulse output of the encoder as a 3-digit number for
motor 2. The first digit is the numerator and the second and third digits set the denominator.

The dividing ratio = (1 + x)/yz when the setting value is a 3-digit value (xyz).

001

(001 - 032, 102 - 132 (1 - 1/

F1-36

(03B5)

Encoder 2 PCB Disconnect
Detect

Sets the function that enables and disables detection of a disconnected encoder connection cable to
cause

PGoH [Encoder (PG) Hardware Fault]

for motor 2.
