Fig. 2-10 Connecting the braking kit to the Drive
TA-TB and TA-TC are contacts of relay used for
outputting fault indicating signal, and TH1 and TH2 are
contacts of temperature relay (relay used for outputting
over-heat indicating signal).
B. Main functions of braking kit
Activation voltage for braking is adjustable;
Protection against excessive duty-cycle of braking
resistor;
Overheat protection of heatsink;
Alarm indication for power module’s fault;
Fault indication and indication for fault relay output;
The braking resistor will be disconnected automatically if
it is over-heated and the relay will output alarming
signal.
The cables connected between the braking kit and the
drive, and those between the braking kit and braking
resistor should be less than 5m. If longer than 5m,
twisted-pair cable should be used and the maximum
length is 10m.
2.3.3 Communication Parts
1. Communication cables
A. Cables of operation panel
Model: TDC-CB0015(1.5m)
TDC-CB0030(3.0m)
The cables are used to connect the panel to the drive.
B. Communication cables of remote mounted keypad
Two models: FRC21W1(3.0m) FRC21W2(30m)
The cables are used to connect the remote mounted
keypad to the drive.
2. Remote mounted keypad
Model: TDO-RC02
It uses the same structure with operation panel of the
drive. It is easily to be installed and secured and
convenient for hand-held operation. Its display is similar
to the operation panel.
RS485 communication mode is used between the drive
and the remote mounted keypad. A 4-core cable is used
to connect the drive and the keypad, and the maximum
distance can be 1000m. Master/slave communication
mode is used. The keypad is the master and the drive is
the slave. Cable terminals can be secured by common
screws, which makes it convenient for maintenance.
One remote mounted keypad can control several drives
by connecting the communication cables of 485+ and
485- of each drive to form a RS485 network.
Functions:
1) Be able to control the start, stop, jog operation, fault
reset of slave drives and change the frequency settings
and operation direction.
2) Identify the type of slave machine automatically. Be
able to monitor the operating frequency, frequency
setting, output voltage and current, analog close-loop
feedback, analog close-loop setting and external
counting value automatically.
3. Fieldbus adapter
Model: TDS-PA01
Be able to connect ENYDRIVE drive to PROFIBUS
network via the TDS-PA01 fieldbus adapter. In the
PROFIBUS network system, the drive operates as a
slave.
Functions:
1) To send control commands to drive (such as: start,
stop and jog);
2) To send speed or frequency reference signal to the
drive;
3) To read operating status information and actual
values from the drive;
4) To reset the drive when fault occurs in it.
4. DrvWindows host monitoring software
Version: DrvWindows V1.2
Used in the control network formed by TD1000, TD2000
and TD2100 series drive via RS485 bus. It can monitor
the operating status of the drive connected to the bus
and realize the central management of the drive. The
software’s friendly interfaces make the operation
convenient. This software now support EV2000 drive.
Functions:
Polling of slave drives, frequency setting, operating and
stopping, changing and querying the settings of
parameter.
5. Keypad Holder
Model: EVF-KB02
