SIEPC71061737B GA800 Drive Technical Reference
After you set the number of gear teeth, the drive uses this formula to calculate the motor speed:
Note:
When
F1-12 = 0
or
F1-13 = 0
, the gear ratio is 1.
■
F1-13: Encoder 1 Gear Teeth 2
No.
(Hex.)
Name
Description
Default
(Range)
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
(0 - 1000)
After you set the number of gear teeth, the drive uses this formula to calculate the motor speed:
Note:
When
F1-12 = 0
or
F1-13 = 0
, the gear ratio is 1.
■
F1-14: Encoder Open-Circuit Detect Time
No.
(Hex.)
Name
Description
Default
(Range)
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]
.
2.0 s
(0.0 - 10.0 s)
If the drive does not detect output pulses from the encoder for longer than the time set in
F1-14
, the drive will detect
PGo
.
Note:
Motor speed and load conditions can cause
ov [Overvoltage]
and
oC [Overcurrent]
faults.
■
F1-17: Deviation 2 Detection Selection
No.
(Hex.)
Name
Description
Default
(Range)
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
.
10
(0 - 100)
When
F1-17 = 0
, the drive will not detect
dv2
.
■
F1-18: Deviation 3 Detection Selection
No.
(Hex.)
Name
Description
Default
(Range)
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]
.
10
(0 - 10)
When the drive detects these two conditions at the same time for the number of times set in
F1-18
, the drive will
detect
dv3
.
•
The torque reference and acceleration are in opposite directions. For example, torque reference is in forward run
and the acceleration is in a negative direction.
•
The difference between the speed reference and the actual motor speed is more than 30%.
Note:
•
Reference the setting value for
E5-11 [Encoder Z-Pulse Offset]
and the δθ value found on the motor nameplate. A usual cause for a
dv3
fault is an incorrect
E5-11
setting.
•
Set
F1-18 = 0
to disable the function.
