APEX615n Installation Guide

Problem

Cause

Solution

No RS-232C
Communication

1. Improper RS-232C Interface or

communication parameters

2. RS-232C disabled

3. In daisy chain, unit may not be set to

proper address

1. See

RS-232C Troubleshooting section

2. Enable RS-232C with the

command (all units if daisy-chained)

3. Verify proper application of the

ADDR

command

No Torque/Force

1. Improper wiring
2. No power to motor
3. Shutdown issued

1. Check wiring to the motor, as well as other system wiring
2. Check power at motor
3. Enable drive with

DRIVE1

Power-up Program does
not execute

1. ENABLE IN input is not grounded to

GND

STARTP

program is not defined

1. Ground ENABLE IN to GND and reset or cycle power

2. Check the response to the

STARTP

command. If no program is

reported, define the

STARTP

program and reset

Program access denied:
receive the message

*ACCESS DENIED

when

trying to use the

DEF

DEL

ERASE

INFNC

, or

MEMORY

commands

1. Program security function has been

enabled (

INFNCi-Q

) and the

program access input has not been
activated

1a.

Activate the assigned program access input, perform your
programming changes, then deactivate the program access input.

1b.

Refer to the instructions in the

INFNC

command description in the

6000 Series Software Reference

Program execution: stops
at the

INFEN1

command

INFEN1

enables drive fault

monitoring, but the drive fault level
(

DRFLVL

) command is set

incorrectly for the drive being used.

1. Issue the correct

DRFLVL

command for your drive (refer to the

DRFLVL

command)

Program execution: the
first time a program is run,
the move distances are
incorrect. Upon
downloading the program
the second time, move
distances are correct.

1. Scaling parameters were not issued

when the program was downloaded;
or scaling parameters have been
changed since the program was
defined

1. Issue the scaling parameters (

SCALE1

SCLA

SCLD

SCLV

) before

saving any programs

Programmable inputs not
working

1. IN-P or AUXP (input pullup) not

connected

2. If external power supply is used, the

grounds must be connected together

3. Improper wiring

1a.

When inputs will be pulled down to 0V by an external device,
connect IN-P and/or AUX-P to +5V or to another positive supply

1b.

When inputs will be pulled up to 5V or higher by an external device,
connect IN-P and/or AUX-P to 0V

2. Connect external power supply’s ground to ISO GND

3. Check wiring for opens, shorts, and mis-wired connections

Programmable outputs not
working

1. Output connected such that it must

source current (pull to positive
voltage)

2. OUT-P not connected to +5V or

other positive voltage source

3. If external power supply is used, the

grounds must be connected together

4. Improper wiring

1. Outputs are open-collector and can only sink current–change wiring.

2. Connect OUT-P to +5V supplied or other voltage in system

3. Connect external power supply’s ground to ground ISO GND

4. Check wiring for opens, shorts, and mis-wired connections

Trigger, home, or end-of-
travel inputs not working.

1. If external power supply is used, the
grounds must be connected together.

2. Improper wiring.

1. Connect external power supply's ground to APEX615n's ground .
2.a. Check wiring for opens, shorts, and mis-wired connections.
2.b. When inputs are pulled down to 0V by an external device, connect

AUX-P to +5V supplied or to an ex5-24V supply (but not to
both).

2.c. When inputs are pulled to 5-24V by external device, connect AUX-P

to 0V.

2.d. Make sure a 5-24V power source is connected to the V_I/O terminal.

Wrong Direction—
Stable

1. Phase of encoder reversed

1. Switch CHA+ with CHA- connection from APEX615n to encoder

Wrong Direction—
Unstable

1. Not tuned properly
2. Phase of encoder reversed

1. Refer to Chapter 4 for tuning instructions
2. Switch CHA+ with CHA- connection from APEX615n to encoder

Wrong Speed or Distance

1. Wrong resolution setting
