Control Profile; Profidrive Control Profile - Danfoss VLT Midi Drive FC 280 Programming Manual

Control
4.2.4 Process Control Operation
In process control operation, parameter 1-00 Configuration
Mode is set to [3] Process.
The reference range in parameter 3-00 Reference Range is
always [0] Min - Max.
•
MRV is the process setpoint.
•
MAV expresses the actual process feedback (range
±200%).
4.2.5 Influence of the Digital Input
Terminals on FC Control Mode
In parameter 8-50 Coasting Select to
parameter 8-58 Profidrive OFF3 Select, set the influence of
the digital input terminals on the control of the frequency
converter.
NOTICE
The setting of parameter 8-01 Control Site overrules the
settings in parameter 8-50 Coasting Select to
parameter 8-58 Profidrive OFF3 Select. The setting of
terminal 37 coast stop (safe) overrules any other
parameter.
Program each of the digital input signals to logic AND,
logic OR, or to have no relation to the corresponding bit in
the control word. In this way, the following signal sources
initiate a specific control command, for example stop/
coast:
•
Fieldbus only.
•
Fieldbus AND digital input.
•
Either fieldbus OR digital input terminal.
NOTICE
To control the frequency converter via PROFIBUS, set
parameter 8-50 Coasting Select to either [1] Bus or [2]
Logic AND. Then set parameter 8-01 Control Site to [0]
Digital and ctrl.word or [2] Controlword only.
For more detailed information and examples of logical
relationship options, see chapter 8 Troubleshooting.

4.3 Control Profile

Control the frequency converter according to:
•
The PROFIdrive profile, see chapter 4.4 PROFIdrive
Control Profile, or
•
The Danfoss FC control, see chapter 4.5 Danfoss
FC Control Profile.
Select the control profile in parameter 8-10 Control Word
Profile. The choice of profile affects the control word and
status word only.

Programming Guide
Chapter 4.4 PROFIdrive Control Profile and
chapter 4.5 Danfoss FC Control Profile provide a detailed
description of control and status data.

4.4 PROFIdrive Control Profile

This section describes the functionality of the control word
and status word in the PROFIdrive profile.
4.4.1 Control Word According to
PROFIdrive Profile (CTW)
The control word is used to send commands from a master
(for example a PC) to a slave.

Table 4.5 Control Word Bits
Explanation of the control bits
Bit 00, OFF 1/ON 1
Normal ramp stops using the ramp times of the actual
selected ramp.
Bit 00 = 0 stops and activates the output relay if the
output frequency is 0 Hz, and if [31] Relay 123 is selected
in parameter 5-40 Function Relay.
When bit 0 = 1, the frequency converter is in state 1,
Switching on inhibited.
Refer to Illustration 4.4.
Bit 01, OFF 2/ON 2
Coast stop.
Bit 01 = 0 coast stops and activates the output relay if the
output frequency is 0 Hz, and if [31] Relay 123 is selected
in parameter 5-40 Function Relay.
When bit 01 = 1, the frequency converter is in state 1,
Switching on inhibited. Refer to Illustration 4.4.
Bit 02, OFF 3/ON 3
Quick stop using the ramp time of parameter 3-81 Quick
Stop Ramp Time.
