Table 4.4 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" leads to the stop and activation of the output
relay 1 or 2 if the output frequency is 0 Hz and if [Relay
123] has been selected in 5-40 Function Relay.
When bit 0="1", the frequency converter is in State 1:
"Switching on inhibited".
Refer to Illustration 4.1.
Bit 01, OFF 2/ON 2
Coasting stop
When bit 01="0", a coasting stop and activation of the
output relay 1 or 2 occurs if the output frequency is 0 Hz
and if [Relay 123] has been selected in 5-40 Function Relay.
When bit 01="1", the frequency converter is in State 1:
"Switching on inhibited". Refer to Illustration 4.1.
Bit 02, OFF 3/ON 3
Quick stop using the ramp time of 3-81 Quick Stop Ramp
Time. When bit 02="0", a quick stop and activation of the
output relay 1 or 2 occurs if the output frequency is 0 Hz
and if [Relay 123] has been selected in 5-40 Function Relay.
MCA 122 Modbus TCP
When bit 02="1", the frequency converter is in State 1:
"Switching on inhibited".
Refer to Illustration 4.1.
Bit 03, Coasting/No coasting
Coasting stop Bit 03="0" leads to a stop. When bit 03="1",
the frequency converter can start if the other start
conditions are satisfied.
NOTICE
The selection in 8-50 Coasting Select determines how bit 03
is linked with the corresponding function of the digital
inputs.
Bit 04, Quick stop/Ramp
Bit=1
Quick stop using the ramp time of 3-81 Quick Stop Ramp
ON 1
Time.
ON 2
When bit 04="0", a quick stop occurs.
ON 3
When bit 04="1", the frequency converter can start if the
No coasting
other start conditions are satisfied.
Ramp
NOTICE
Use ramp
The selection in 8-51 Quick Stop Select determines how bit
Start
04 is linked with the corresponding function of the digital
Reset
inputs.
Jog 1 ON
Jog 2 ON
Bit 05, Hold frequency output/Use ramp
Data valid
When bit 05="0", the current output frequency is being
Slow down
maintained even if the reference value is modified.
Catch up
When bit 05="1", the frequency converter can perform its
Selection lsb
regulating function again; operation occurs according to
Selection msb
the respective reference value.
Reverse
Bit 06, Ramp stop/Start
Normal ramp stop using the ramp times of the actual
ramp as selected. In addition, activation of the output relay
01 or 04 if the output frequency is 0 Hz if Relay 123 has
been selected in 5-40 Function Relay. Bit 06="0" leads to a
stop. When bit 06="1", the frequency converter can start if
the other start conditions are satisfied.
NOTICE
The selection in 8-53 Start Select determines how bit 06 is
linked with the corresponding function of the digital
inputs.
Bit 07, No function/Reset
Reset after switching off.
Acknowledges event in fault buffer.
When bit 07="0", no reset occurs.
When there is a slope change of bit 07 to "1", a reset
occurs after switching off.
Bit 08, Jog 1 OFF/ON
Activation of the pre-programmed speed in 8-90 Bus Jog 1
Speed. JOG 1 is only possible if bit 04="0" and bit
00-03="1".
