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 1 or 2 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 1 or 2
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.
Bit 02=0 quick stops and activates the output relay 1 or 2
if the output frequency is 0 Hz, and if [31] Relay 123 is
selected in parameter 5-40 Function Relay.
When bit 02=1, the frequency converter is in state 1,
Switching on inhibited.
Refer to Illustration 4.4.
Bit 03, coasting/no coasting
Bit 03=0 leads to a coast stop.
When bit 03=1, if the other start conditions are fullled,
the frequency converter can start.
NOTICE
The selection in parameter 8-50 Coasting Select
determines how bit 03 is linked with the corresponding
function of the digital inputs.
Bit 04, quick stop/ramp
Quick stop using the ramp time of parameter 3-81 Quick
Stop Ramp Time.
When bit 04=0, a quick stop occurs.
When bit 04=1, if the other start conditions are fullled,
the frequency converter can start.
NOTICE
The selection in parameter 8-51 Quick Stop Select
determines how bit 04 is linked with the corresponding
function of the digital inputs.
Bit 05, hold frequency output/use ramp
When bit 05=0, the present output frequency is
maintained, even if the reference value is modied.
When bit 05=1, the frequency converter can perform its
regulating function again according to the respective
reference value.
Bit 06, ramp stop/start
Normal ramp stop using the ramp times of the actual
ramp selected. In addition, if [31] Relay 123 is selected in
parameter 5-40 Function Relay, and if the output frequency
is 0 Hz, this bit activates output relay 01 or 04.
Bit 06=0 stops the frequency converter.
When bit 06=1, if the other start conditions are fullled,
the frequency converter can start.
NOTICE
The selection in parameter 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 o. Acknowledges event in fault
buer.
When bit 07=0, no reset occurs.
When there is a slope change of bit 07 to 1, a reset occurs
after switching o.
Bit 08, jog 1 OFF/ON
Activation of the pre-programmed speed in
parameter 8-90 Bus Jog 1 Speed. JOG 1 is only possible if bit
04=0 and bits 00–03=1.
Bit 09, jog 2 OFF/ON
Activation of the pre-programmed speed in
parameter 8-91 Bus Jog 2 Speed. JOG 2 is only possible if bit
04=0 and bits 00–03=1.
