There are two analogue outputs and three relay outputs in the ACS 600

for the external supervision purposes. By default, analogue output AO1

gives the motor speed and AO2 the motor current as 0 to 20 mA

current signal. The relay outputs give the indications ready (RO1),

running (RO2) and no fault (RO3).

The actual signals shown on the Control panel display are speed,

torque and control location.

It is possible to supervise the M/F Link with Parameters 30.18 COMM

FAULT FUNC and 30.19 COMM FAULT TIMEOUT. Parameter 30.18

defines the action (NO/FAULT/WARNING) when an error is detected on

the M/F Link. Parameter 30.19 sets the time between the detection and

the action defined by Parameter 30.18. For more information, see the

Firmware Manual, Appendix C .

CAUTION! The Follower does not send any feedback data to the

Master. Therefore it is recommended to separately wire the fault

information of the Follower to the Master. See Chapter 2 – Installation

and M/F Link Specification .

If speed measurement is required with Master or Follower stations, the

NTAC-02 Pulse Encoder Interface Module must be connected to

channel CH1. The following parameter values must also be set:

• 50.04 ENCODER CHANNEL: CHANNEL1

• 70.03 CH1 BAUDRATE: 4 Mbit/s.

Note that the new parameter values take effect only after the power to

the drive and the NTAC-02 module are switched off and on.
