Channel setting with encoder, DB405
For the automatic control unit to measure current and output correctly, C202 must be set to 4, frequency converter.
When a frequency converter is used with the automatic control unit, EP104 or E105, a load guard with personal protection
cannot be used. When C202 is set to 4, the personal protection is automatically disabled and channels C230 and C240 are
hidden. Depending on the selected setting in C200, the values in C211, C212, C232, C233, C242 and C243 should be
adjusted so that satisfactory function and reliable mechanical protection is obtained for the gate or door.
A basic setting for the motor cutout is 4.0 A in channels C252, C253, C262 and C263 and 5.0 seconds in channel C221.
Adjust the settings so that adequate function and safe protection for the motors is obtained.
When a frequency converter is used, only the upper limit is active for the internal motor cutout. This limit is 50% than the
set value. If 4.0 A has been indicated, the current limit is 6.0 A. If the current is above this limit during the time in C221,
the control unit will stop and show the error code E201 for motor 1 or E202 for motor 2.
In the channel group F, settings are made for how the frequency converter is to work together with EP104 or EP105.
The automatic control unit checks and controls the frequency converters using serial communication. If there are problems
with communication or when communication is disabled, via F001, the frequency converters can be operated in hold-to-run
at the same speed in both opening and closing, by changing channel 02-00 on the frequency converter to a 4 for the rotatory
actuator or 0 to use the arrow keys to adjust the F-value. Note that when the rotatory actuator is turned clockwise the
output frequency increases, so start by turning it to the maximum extent anticlockwise and then increase to a suitable output
frequency. If communication errors occur or if communication is disabled, the motors can only be operated using hold-to-
run. In hold-to-run in this mode, no ramping down takes place before open or closed position is reached. For this reason,
adjust the speed and pay attention when the open or closed position is close.
For the speed settings in F012, F013, F022 and F023 to work, the ratio of the motor winder must be specified in the
following channels:
F030 = motor winder connected to motor 1.
F040 = motor winder connected to motor 2.
Until ratio has been selected in these channels, maximum speed will be limited to 25Hz. If the ratio is not stated in the
documentation belonging to the motor winder, a measurement can be done by displaying channel F031 or F041 and then
letting the motor winder open or close until a value appears after approx. 6 seconds in these channels. Compare this value
with the values specified in the instruction manual for channel F030 or F040 and specify the corresponding figure in both
these channels.
It is specified in channels F002, F003 and F004 how quickly the gate or door is to reach its opening or closing speed.
F002 = Acceleration from fully closed position.
F003 = Acceleration in all other starts. To obtain an even and jerk-free start in the fully open position, the time in F003
must be adjusted for this particular start.
F004 = Acceleration when P500 is programmed to 2, Battery backup, and activated.
It is specified in channels F005 and F006 how quickly the gate or door is to stop.
F005 = Retardation time for limit switches and change of direction.
F006 = Retardation time for photocell and vehicle loops.
The times in these four channels refer to a speed which is 100Hz, i.e. the times apply when the speed is 100Hz. If the
speed is lower, for example 50Hz, the time will be halved, but the force in deceleration and speed increase will be the same
regardless of speed. If the times increase, the forces on the gate or door decrease in changes of speed.
The factory settings are adapted to a swing gate with a 6 metre opening. Check that the gate accelerates without subsequent
swings from both the closed and open positions. Increased times reduce the risk of swings. Check also that the gate slows
down gently and without jerking in the open and closed positions. With the photocell or vehicle loop activated, deceleration
must take place so that no collision between the gate and the vehicle can occur. Check and adjust the time in F006.
In the case of a sliding gate, the value must be specified in F002 and F003. Adapt the acceleration to the size and weight of
the gate. A reasonable starting value is 5.0 seconds. The retardation in F005 and F006 is adjusted in the same way as above.
The readout channels in L114, L115, L124 and L125 cannot be adjusted when the C202 has been chosen for 4 frequency
converters. These channels show the calculated angle, before the limit, where the motors will go down to low speed in
accordance with F008 and F009. This calculated angle depends on speed, slow speed, retardation and chosen ratio. The
angles in these channels are calculated continuously on the basis of these parameters. If stopping at the specified angle
for open or closed position takes place too abruptly, there is a possibility of adding a certain angle to the values in these
channels. This extra deceleration angle is specified in channels F014, F015, F024 or F025.
