tmcm - 1160 v1.01 hard ware manual (rev. 1.02 / 2013 - jul - 23 ) 8 www.trinamic.com 3.2.1 power connector this module offers separate power supply inputs for digital logic (pin 2) and driver/power stage (pin 1). both supply inputs use common ground connections (pin 4). this way, power supply for the driver stage may be switched off while still maintaining position and status information when keeping digital logic supply active. due to internal diode the digital logic supply has to be equal or higher than the driver/power stage sup ply. otherwise the diode between driver/power stage supply and digital logic supply might short the separate supplies. +u d river supply only in case power supply is provided only to the power section (pin 1) an internal diode will distribute power to the logic section. so, when separate power supplies are not required it is possible to just use pin 1 and 4 for powering the module. if so, pin 2 (logic supply) and pin 3 (/shutdown in put) can be connected together in order to enable the driver stage. e nabling the driver s tage connect /shutdown input to +u driver or +u logic in order to activate the driver stage. leaving this input open or connecting it to ground will disable driver stag e . a 4 - pin jst eh series b4b - eh connector is used as power connector on - bo ard. pin label description 1 +v driver module + driver stage power supply input 2 +v logic (optional) separate digital logic power supply input 3 /shutdown shutdown input. connect this input to +v driver or +v logic in order to activate driver stage. leaving this input open or connecting it to ground will disable driver stage 4 gnd module ground (power supply and signal ground) table 3 . 2 connector for power supply 3.2.1.1 power supply for proper operation care has to be taken with regard to the power supply concept and design. due to space restrictions the tmcm - 1160 includes about 20 f / 100 v of supply filter capacitors. these are ceramic capacitors which have been selected for high reliability and long life time. h ints for power supply cables - k eep power supply cables as short as possible . - u se large diameters for power supply cables . c autio n ! add external power supply capacitors! it is recommended to connect an electrolytic capacitor of significant size (e.g. 2200 f / 63 v) to the power supply lines next to the tmcm - 1 160 especially if the distance to the power supply is large (i.e. more than 2 - 3m) ! rule of thumb for size of electrolytic capacitor: in addition to power stabilization (buffer) and filtering this added capacitor will also reduce any voltage s pikes which might otherwise occur from a combination of high inductance power supply wires and the ceramic capacitors. in addition it will limit slew - rate of power supply voltage at the module. the low esr of ceramic - only filter capacitors may cause stabil ity problems with some switching power supplies. 4 1
tmcm - 1160 v1.01 hard ware manual (rev. 1.02 / 2013 - jul - 23 ) 9 www.trinamic.com do not connect or disconnect motor during operation! motor cable and motor inductivity might lead to voltage spikes when the motor is disconnected / connected while energized. these voltage spikes might exceed voltage limits of the driver mosfets and might permanently damage them. therefore, always disconnect power supply before connecting / disconnecting the motor. keep the power supply voltage below the upper limit of 51 v! otherwise the driver electronics will seriously be damaged! especially, when the selected operating voltage is near the upper limit a regulated power supply is highly recommended. please see also chapter 7 (operating values). there is no reverse polarity protection! the module will short any reversed supply voltage due to internal diodes of the driver transistors. 3.2.2 serial communication connector the module supports rs485 and can communication via this connector. can interface will be de - activated in case usb is connected due to internal sharing of hardware resources. a 2mm pitch 5 - pin jst b5b - ph - k connector is used for serial communication. pin label description 1 can_h can bus signal (dominant high) 2 can_l can bus signal (dominant low) 3 gnd module ground (system and signal ground) 4 rs485+ rs485 bus signal (non inverted) 5 rs485 - rs485 bus signal (inverted) table 3 . 3 connector for serial communication 3.2.2.1 rs485 for remote control and communication with a host system the tmcm - 1160 provides a two wire rs485 bus interface. for proper operation the following items should be taken into account when setting up an rs485 network: 1. bus structure : the network topology should follow a bus structure as closely as possible. that is, the connection between each node and the bus itself should be as short as possible. basically, it should be short compared to the length of the bus. figure 6.4 bus structure 2. bus termination : especially for longer busses and/or multiple nodes connected to the bus and/or high communication speeds, the bus should be properly terminated at both ends. the tmcm - 1160 does offer on - board termination resistors which can be activated with the help of a jumper. the ju mper has to be removed for units not connected to one end of the bus! 1 5 c : > n o d e 1 n o d e n - 1 n o d e n h o s t s l a v e s l a v e s l a v e r s 4 8 5 t e r m i n a t i o n r e s i s t o r ( 1 2 0 o h m ) t e r m i n a t i o n r e s i s t o r ( 1 2 0 o h m ) } k e e p d i s t a n c e a s s h o r t a s p o s s i b l e
