2.1.8 Freeze Mode (25, 26)
If desired, the frequency of the drive can be frozen at its present value. The mode is indicated by data point 25. It is an option available when serial interface is
lost.
2.1.9 Coast (27, 28)
The coast command (28) shuts down the inverter and makes the motor freewheeling, which normally brings it to stand still. The drive cannot be restarted in any
mode before the coast command is removed. It is, therefore, often used as a safety interlock. Data point 27 indicates when the drive is coasted.
2.1.10 Motor Accel and Decel Rate (31, 32)
The time to accelerate or decelerate the drive between 0 Hz and the motor’s nominal frequency can be programmed. The drive is capable of settings between
one to 3600 seconds (one hour). Only Ramp1 is accessible from the FLN network.
2.1.11 Hand/Auto Modes (34)
The SEL HND.AUTO shows which mode the drive is in. The drive can be commanded into either Hand or Auto mode by pressing the respective keys on the keypad
of the drive. Hand mode disables any programmed control strategies and allows the drive keypad to be used to set the drive speed. The only serial communication
command that can override Hand mode is data point 28, CMD COAST.
2.1.12 Run Enable (35)
Set data point 35 to ON to run the drive from the FLN with default drive parameter settings. In the OFF mode, the drive will run only in Hand mode or in Auto mode
from the drive‘s digital control terminals. par. O-53 Start Select, controls the interaction of point 35 and the digital run command.
2.1.13 Bus Functions (36, 37)
The amount of time the drive will wait between communication packets is programmable. If the time is exceeded, the drive will assume serial communication
has stopped and respond with programmable choices. The drive can ignore the loss, freeze its current output, stop, run at a predetermined jog frequency, run at
maximum output frequency or stop and trip while issuing an alarm. Wait time is selected at point 36 and the function after a timeout at point 37. See descriptions
for par. E-74 Pulse Output Max Freq #29 and par. E-75 Terminal X30/6 Pulse Output Variable in the AF-600 FP Programming Guide.
2.1.14 Jog Frequency and Command (38, 39)
The Jog Frequency can be set by data point 38. Setting data point 39 to [On] will cause the frequency converter to send the Jog Frequency to the motor.
2.1.15 Relay Out 1, 2 (40, 41, 43, 44)
Two programmable relay outputs (Form C, 240 VAC, 2 Amp) are available. These can be triggered through the serial bus by command points 40 and 41. This allows
the FLN to utilize the drive’s built-in relays as additional network programmable relays. The data points 43 and 44 indicate whether the relay is triggered or not
(On/Off). Parameters
E-24.0 and E-24.1, Function Relay 1 and Function Relay 2, must be set to [45] Bus controlled, [46] Bus controlled 1, if timeout or [47] Bus
controlled 0, if timeout.
2.1.16 PID Control Functions (61-65)
The drive has a sophisticated built-in proportional, integral, derivative (PID) controller. The PID controller is activated by setting par. H-40 Configuration Mode, to
Closed loop through the drive’s keypad.
