Control-Signal Diagnostics
Introduction
On the display terminal, the [Display] MON-, [Communication map] CMM- submenu can be used to
display control-signal diagnostic information between the drive and the controller:
 Active command channel [Command Channel] CMdC
 Value of the control word [Cmd Register] CMd from the active command channel [Command Channel]
CMdC
 Active reference frequency channel [Ref Freq Channel] rFCC
 Value of the reference frequency [Pre-Ramp Ref Freq] FrH from the active target channel [Ref Freq
Channel] rFCC
 Value of the operating state word [CIA402 State Reg] EtA
 Specific data for all available fieldbus are in dedicated submenus.
 In the [Command word image] CWI- submenu: control words from all channels
 In the [Freq. ref. word map] rWI- submenu: reference frequency values produced by all channels
Control Word Display
The [Command Channel] CMdC parameter indicates the active command channel.
The [Cmd Register] CMd parameter indicates the hexadecimal value of the control word (CMD) used to
control the drive.
The [Command word image] CWI- submenu [CANopen Cmd.] CMd2 parameter is used to display the
hexadecimal value of the control word from he fieldbus module.
Reference Frequency Display
The [Ref Freq Channel] rFCC parameter indicates the active channel for reference frequency.
The [Ref Frequency] LFr parameter indicates the value (in 0.1 Hz units) of the reference frequency used
to control the drive.
The [Freq. ref. word map] rWI- submenu [CAN Ref Freq] LFr2 parameter is used to display the
value (in 0.1 Hz units) of the reference frequency from the fieldbus.
Operating State Word Display
The [CIA402 State Reg] EtA parameter gives the value of the operating state word (ETA).
The table provides the bit details of ETA parameter:
Bit Description
DRIVECOM Status word
Bit0 = 1 Ready to switch on
Bit1 = 1 Switched on
Bit2 = 1 Operation enabled
Bit3 = 1 Operating state fault
Bit4 = 1 Power stage is switched on
Bit5 = 0 Quick stop
Bit6 = 1 Switch on disabled
Bit7 = 1 Warning
Bit8 = 1 Drivecom reserved
Bit9 = 0 Forced local mode in progress
Bit10 = 1 Reference value reached (steady state)
Bit11 = 1 Reference value exceeded (< LSP or > HSP)
Bit12 Reserved
Bit13 Reserved
Bit14 = 1 Stop imposed via STOP key
Bit15 = 0 Motor rotation in forward direction (or stopped)
