MHT260a (Engl.)
(14) System parameter 86［Basic type, SX bus, T-link］
Connects the NTC thermistor of braking resistor to the control input terminal to protect the resistor.
Para. Name Setting Initial value Change
86 Braking resistor thermal relay 0: Electronic thermal relay
1: External thermal relay
0 Power
Setting Overheat detection of braking resistor
0: Electronic thermal relay Calculates the regenerated power by amplifier to protect the resistor.
1: External thermal relay Directly detects resistor overheat using NTC thermistor built-in the resistor.
To use external thermal relay, assign the external fault input (34) at the control allocation terminal, connect NTC thermistor for the external
resistor.
Protective function by electronic thermal relay built-in the amplifier will be disabled.
(15) System parameter 87, 88［Basic type, SX-bus, T-link］
(a) Basic type
Para. Name Setting range Initial value Change
87 CONT always valid 1 0 to 74 (in 1 step) 0 Power
88 CONT always valid 2 0 to 74 (in 1 step) 0 Power
(b) SX bus, T-link
Para. Name Setting range Initial value Change
87 CONT always valid 1 0 to 55 (in 1 step) 0 Power
88 CONT always valid 2 0 to 55 (in 1 step) 0 Power
Arbitrary signals among the control input signals can be always valid.
