Fn53
: DC braking time coast stopping restart time
(unit
0.1
sec.)
Range: 0/ 0.1~25.5 sec.
DC braking injection can prevent overrun of motor at end of deceleration.
Select proper time according to the load condition. DC braking operation enabled when

: DC braking injection frequency
(unit
0.1
Hz)
Range: 0/1-10Hz.
Fn54=0
: Inverter coasts to stop. (Immediate brake on) See warning below.
Fn54=1-10
: 1-10Hz (unit 0.1 Hz), Inverter ramp down and DC braking will be enabled when output

Table 5.3k Inverter stopping modes.
WARNING: If inverter is set to coast to stop mode the motor must be at rest before the next
run signal is commanded. If not, damage to inverter may occur.
* CAUTION: If coast to stop (base block) is used make sure motor is at rest before inverter is
restarted or damage may result.
Fn55
: DC braking level
Fn55
defines the percentage of DC injection braking voltage to the full input voltage.
For example, set
Fn53=0.5
,
Fn54=2
,
Fn55=8
(input voltage=220V) DC braking will start when
inverter decelerates, to 2Hz (
Fn54
) and inject 17.6 VDC (220 x 8%,
Fn55
) for 0.5 sec. (
Fn53
).
Fn56:
Baud rate of serial RS232 'Command Link' communication.
Please refer to KN232
'Command Link' communication operation manual. Normally 9600 bps is the required setting when
using the KN232 link communication package.
Fn56=0
: 2400 bps
Fn56=1
: 4800 bps
Fn56=2
: 9600 bps (Factory setting)
Fn56=3
: 19200 bps
Fn57
: Communication command response mode of KN232 'command link'.
Please refer to
communication operation manual. Normal setting is 1 when using the KN232 link package.
Fn58
: Communication transmit object of serial KN232 'Command Link'.
Please refer to
communication operation manual. Normal setting is 0 when using the KN232 link package.
Fn59
: Elapsed trip timer 'Maintenance Sentinal' range 0(OFF)/ 0.5-999 hours.
This function is an exclusive feature of the Crane Commander drive. It provides a programmable
trip time after the alloted running time has accumulated. The Crane Commander's display will flash
a
ELF
fault. Manual reset is required to reset the
ELF
fault.
