CN1-17 This is an ABS transfer mode request device.
When "_ _ _ 1" is set in [Pr. PA03] and absolute position detection system
by DIO is selected, CN1-17 pin will become ABSM. (Refer to chapter 12.)
CN1-18 This is an ABS request device.
When "_ _ _ 1" is set in [Pr. PA03] and absolute position detection system
by DIO is selected, CN1-18 pin will become ABSR. (Refer to chapter 12.)
This is used when the semi closed loop control/fully closed loop control
switching is enabled with [Pr. PE01].
Turn off CLD to select the semi closed loop control, and turn on CLD to
select the fully closed loop control.
Turn on MECR to clear the motor-side/load-side position deviation counter
to zero.
- It operates during the fully closed loop control.
- It does not affect the position control droop pulses.
- Turning on this device during the semi closed loop control does not affect
the operation.
- Turning on this device while the fully closed loop control error detection
function is disabled in [Pr. PE03] does not affect the operation.
Connector
pin No.
CN1-48 When an alarm occurs, ALM will turn off.
When an alarm does not occur, ALM will turn on after 2.5 s to 3.5 s after
power-on.
When [Pr. PD34] is "_ _ 1 _", an alarming or warning will turn off ALM.
When using the signal, enable it by setting [Pr. PD23] to [Pr. PD26] and
[Pr. PD28]. DB turns off when the dynamic brake needs to operate. When
using the external dynamic brake on the servo amplifier of 11 kW or more,
this device is required. (Refer to section 11.17.)
For the servo amplifier of 7 kW or less, it is not necessary to use this
device.
CN1-49 Enabling servo-on to make the servo amplifier ready to operate will turn on
RD.
CN1-22 When the number of droop pulses is in the preset in-position range, INP
will turn on. The in-position range can be changed using [Pr. PA10]. When
CN1-24
the in-position range is increased, INP may be on during low-speed
rotation.
INP turns on when servo-on turns on.
When the servo motor speed reaches the following range, SA will turn on.
Set speed ± ((Set speed × 0.05) + 20) r/min
When the preset speed is 20 r/min or less, SA always turns on.
SA does not turn on even when the SON (Servo-on) is turned off or the
servo motor speed by the external force reaches the preset speed while
both ST1 (Forward rotation start) and ST2 (reverse rotation start) are off.
CN1-25 VLC turns on when speed reaches a value limited with any of [Pr. PC05
Internal speed limit 1] to [Pr. PC11 Internal speed limit 7] or VLA (Analog
speed limit).
This turns off when SON (Servo-on) turns off.
TLC turns on when a generated torque reaches a value set with any of [Pr.
PA11 Forward torque limit], [Pr. PA12 Reverse torque limit], or TLA
(Analog torque limit).
