may damage the driver and even cause fire.
The wiring length of the brake unit shall not exceed 10 meters. Twisted
wires or pair wires shall be used and connected in parallel.
Do not connect the brake resistor directly to the DC bus, or it may
damage the servo driver and even cause fire.
c） Connecting terminals (+) and PB of brake resistor:
The connecting terminals of the brake resistor are effective only for the
servo driver of below IS300T050 (inculded) with built-in brake unit.
The prototype of brake resistor can refer to the recommended value and
the wiring length shall be less than 5 meters. Otherwise it may damage
the servo driver.
d） Connecting terminals P and (+) of external reactor:
For the servo driver of above IS300T140 (included)with external reactor,
when assembling, remove the connector between terminals P and (+)
and connect a reactor instead.
e） Terminals U, V, W at the output side of the servo driver:
The servo driver output side cannot connect to the capacitor or surge
absorber. Otherwise, it may cause frequent servo driver protection and
even damage the servo driver.
In case the motor cable is too long, it may generate electrical resonance
easily due to the impact of distributed capacitance, thus damaging the
motor insulation or generating higher leakage current to invoke over
current protection of the servo driver. When the length of motor cable is
longer than 100 meters, it needs to install a AC output reactor.
f） Earth terminal
PE:
This terminal shall be earthed reliably, with resistance of earth cable of
less than 0.1Ω. Otherwise, it may cause fault or damage the servo
driver.
Do not share the earth terminal and zero line of the power supply.
3.2.5 Control terminals and connection:
1）The control circuit terminals are arranged as follows:
